Rutile/anatase TiO2 was incorporated in different amounts (1, 2, 3 and 5
wt.%) in relative to the polyurethane-siloxane (PUS) matrix in order to
investigate the influence of nano-fillers on the hydrophobicity, thermal
properties and morphology of the PUS. A series of PUS nanocomposites
(PUSN) based on α,ω-dixydroxy-ethoxypropyl-poly(dimethylsiloxane)
(EO-PDMS) as the soft segment (SS) and 4,4'-diphenylmethane
diisocyanate (MDI) and 1,4-butanediol (BD) as the hard segment (HS), was
prepared via two-step polyaddition reaction in solvent mixture. Prepared
PUSNs were characterized using FTIR spectroscopy, thermogravimetric
analysis, water absorption, water contact angle and AFM analysis. In
summary, the synthesized PUSNs and especially PUSN with 2 wt.% of TiO2
had better water resistivity and nonwettability, higher thermal stability, and
more pronounced surface morphology that can be potentially used as
protective coatings.
