Surface characterization of polymers by inverse gas chromatography
Ispitivanje površinskih svojstava polimera inverznom gasnom hromatografijom
Abstract
An inverse gas chromatographic (IGC) study of the sorption properties of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), PGME, and PGME modified with ethylene diamine, PGME-en, was presented. At infinite dilution, the thermodynamic parameters of adsorption, the dispersive components of the surface free energies, the acid/base constants and the interaction parameters for the initial and modified copolymer samples were investigated. The adsorption isotherms determined by IGC under conditions of finite surface coverage were used to estimate the surface area, the isosteric heat of adsorption and the adsorption energy distribution on the surface of the initial and modified copolymer samples. .
Na primeru određivanja površinskih karakteristika makroporoznog umreženog poli(glicidilmetakrilat-co-etilenglikoldimetakrilata), PGME, kao i kopolimera modifikovanog sa etilendiaminom, PGME-en, prikazana je mogućnost korišćenja inverzne gasne hromatografije (IGC) za karakterizaciju polimera. Pri nultoj prekrivenosti određeni su termodinamički parametri adsorpcije, disperzivna komponenta slobodne površinske energije, kiselo/bazna svojstva i parametri interakcije osnovnog i modifikovanog kopolimera. Adsorpcione izoterme određene pri konačnoj prekrivenosti korišćene su za određivanje specifične površine, izosterične toplote i raspodele adsorpcione energije na površini osnovnog i kopolimera modifikovanog sa etilendiaminom.
