Preparation and Interaction of Modified PHS and CMC Liquid Composites

Novel liquid composites were successfully prepared by blending copolymer (PEG/PHS) and carboxymethyl cellulose (CMC) in this work. PEG/PHS was achieved by introducing polyethylene glycol (PEG) into the main chain of poly hexanediol succinic (PHS). The results showed that the structure characterization of PEG/PHS was displayed in 1H NMR spectrum. The interaction existed between PEG/PHS and CMC which was validated in FT-IR and SEM. This conjecture was simulated by molecular dynamics under the software YASARA. Because of the existence of interfacial interaction, composites films kept good thermal performance and the flexibility of composite films was greatly improved.
