摘要: The effect of aminosilane on the properties rice straw fiber (RSF) reinforced poly(butylene succinate) (PBS) composites was studied. RSF pretreated with four different coupling agents, 3-aminopropyltriethoxysilane (APTES), 3-aminopropyltrimethoxysilane (APTMES), 3-(2-aminoethylaminopropyl)triethoxysilane (AEAPTES), and 3-(2-aminoethylaminopropyl)-trimethoxysilane (AEAPTMES). results Fourier transform infrared spectroscopy (FTIR) ζ potential measurements confirmed that amino groups were introduced to silane-treated (TRSF) for all silane agents. also indicated a higher degree hydroxyl ion adsorption by surface, which chemically grafted hydroxyl, obtained ethoxy than methoxy silane. This difference might be because relative rates hydrolysis ensuing silanol self-condensation too fast reduce number surface. TRSF composite produced clearly enhanced tensile agents having groups. AEAPTES-RSF-PBS showed highest strength. It content AEAPTES APTES; surface FT-IR react carbonyl PBS form blue-shifted hydrogen bond. water absorption process found follow kinetics mechanisms described Fick's theory. treatment significantly reduced moisture diffusion coefficient but did not change mechanism adsorption. © 2012 Wiley Periodicals, Inc.
