AB  - This study provides a new insight into the relationships between absorption and adsorption processes that occur during the treatment of iPP in aqueous solutions of metal-chloride salts, as well as the impact of these processes on the electrical conductivity of this nonpolar polymer. The polypropylene films (0.5 mm) were exposed to three-day treatments in aqueous solutions of chlorine salts of some alkali and transition metals at temperatures of 22 °C and 80 °C. The treatments induced an increase in the electrical conductivity of iPP, up to 800%. DC conductivity is not directly proportional to the concentrations of metals in the treated films due to the complex relationships between diffusion and adsorption processes. The experiment was set up to simulate the real-world conditions and the study provides practical knowledge on the stability of the electrical conductivity of iPP under exposure to aqueous solutions. The influence of electric aging on the electrical conductivity of the treated films was also examined.

AB  - This paper presents the influence of ageing on the morphological and optical properties of TPD (N,N’-bis(3-methylphenil)-N,N’- diphenylbenzidine) thin films. Understanding of the nucleation mechanism and growth dynamics of molecular thin films is pivotal for controlling their morphology and the film interfacial properties, while the influence of ageing is essential for the potential commercial utilization. Initially, thin films were prepared using a combinatorial physical vapour deposition (CPVD) method, following a cosine-like distribution profile of thickness along monocrystal silica substrate. Morphology of thin films was investigated by using optical (OM) and atomic force microscopy (AFM). The link between optical properties and the resulting thin film morphology was made by spatially correlated morphological (AFM and OM) and optical (absorption and photoluminescence) measurements. The changes in the absorption and photoluminescence spectra are strongly connected to the ageing-induced changes in the microstructure of thin films. Regardless of morphological and differences in the film thickness (two orders of magnitude), all films show amorphous arrangement just after the deposition. Ageing of these films in regular atmosphere conditions results in morphological and changes in optical properties induced by the crystallization. The crystallization of initially amorphous samples was also confirmed by the differentional scanning calorimetry (DSC) measurements. All results indicate the limited possibility of using TPD films in organic electroluminescent devices.

AB  - U ovom radu ispitivan je uticaj gama zračenja na molekulsku masu i staklasti prelaz poli-L-laktida (PLLA). S obzirom da je PLLA pri izlaganju visokoenergijskom zračenju sklon kidanju lanaca i velikoj degradaciji, promene u molekulskoj masi su određene primenom gel propusne hromatografije (GPC). Radijaciono-indukovane promene u staklastom prelazu su ispitane pomoću diferencijalno skenirajuće kalorimetrije (DSC). Prividna aktivaciona energija za staklasti prelaz, ΔH*, određena je na osnovu zavisnosti temperature staklastog prelaza, Tg, od brzine zagrevanja. Kidanje lanaca, uzrokovano zračenjem, glavni je razlog opadanja Tg i ΔH* sa apsorbovanom dozom. Izazvane promene u molekulskoj masi i temperaturi staklastog prelaza odigravaju se na predvidljiv i prilično precizan način. Stoga, gama zračenje može biti korišćeno nesamo za sterilizaciju nego i za dobijanje ovog biomaterijala poželjnih karakteristika.
AB  - The influence of gamma radiation on the structure and glass transition behaviour of poly-L-lactide (PLLA) has been studied. Since PLLA exposed to high-energy radiation in the presence of air is prone to chain scission reactions and large degradation, changes in molecular weight were obtained by the gel permeation chromatography (GPC). Alterations in the glass transition behaviour were investigated by differential scanning calorimetry (DSC). The apparent activation energy, ΔH*, for the glass transition was determined on the basis of the heating rate dependence of the glass transition temperature, Tg. Our findings support the fact that chain scission is the main reason for the decrease of Tg and ΔH* with the absorbed dose. At low doses, despite large changes in molecular weight, only small alterations are observed in the glass transition temperature and apparent activation energy. Further increase in the absorbed dose introduces not only significant changes in the molecular weight but also in the glass transition temperature and the activation energy. Such glass transition behavior is a manifestation of a well-known effect of molecular weight on Tg, postulated by the Fox–Flory equation. However, all the observed alterations are small and tolerable at absorbed doses required for sterilization (up to 25 kGy in most circumstances). Furthermore, this study reveals that the radiation-induced changes in the molecular weight and the glass transition temperature occur in a predictable and fairly accurate manner. Therefore, gamma radiation can be used not only for sterilization but also for tailoring desirable end-use properties of PLLA based implants.

AB  - The influence of orientation on polyolefins was studied in accordance with Peterlin’s molecular model of drawing. Isotactic polypropylene and low density, linear low density and high density polyethylenes were oriented via solid-state stretching at an elevated temperature. Orientation induced changes in the morphology were analyzed by optical and scanning electron microscopy. Differential scanning calorimetry and wide-angle X-ray diffraction were used to determine changes in the crystallinity where a two-stage evolution was revealed. The first stage is characterized by a significant increase in crystallinity while the following saturation occurs with a further draw ratio increase at the second one. The value of the critical draw ratio, which separates these two stages and corresponds to the transformation from the initial to the fully developed fibrillar structure, was influenced by the structural peculiarities of each polyolefin.

AB  - Silver(I) complexes based on itaconic acid hydrogel were prepared and characterized in order to examine the potential use of these materials. FTIR, AFM, in vitro fluid-uptake, metal sorption, and antibacterial activity assay measurements were used for the characterization. Silver(I) ion uptake by hydrogels based on 2-hydroxyethyl methacrylate (HEMA), ethylene glycol dimethacrylate (EGDMA), and different content of itaconic acid (2; 3.5; 5mol%) were determined by inductively coupled plasma mass spectrometry. The coordination sites for metal ions were identified, and the stability in in-vitro condition was determined. Incorporation of silver(I) ions into hydrogels and the influence of these ions on material diffusion properties were analyzed. It was found that the itaconic acid moiety is the determining factor which influences metal ion binding and, therefore, fluid uptake inside the polymer network. Furthermore, obtained hydrogels showed a satisfactory antibacterial activity.

abstract = "Silver(I) complexes based on itaconic acid hydrogel were prepared and characterized in order to examine the potential use of these materials. FTIR, AFM, in vitro fluid-uptake, metal sorption, and antibacterial activity assay measurements were used for the characterization. Silver(I) ion uptake by hydrogels based on 2-hydroxyethyl methacrylate (HEMA), ethylene glycol dimethacrylate (EGDMA), and different content of itaconic acid (2; 3.5; 5mol%) were determined by inductively coupled plasma mass spectrometry. The coordination sites for metal ions were identified, and the stability in in-vitro condition was determined. Incorporation of silver(I) ions into hydrogels and the influence of these ions on material diffusion properties were analyzed. It was found that the itaconic acid moiety is the determining factor which influences metal ion binding and, therefore, fluid uptake inside the polymer network.
