摘要: Poly(N-isopropylacrylamide) (PNIPAAm)/poly(ethylene oxide) (PEO) semi-interpenetrating polymer networks (semi-IPNs) synthesized by radical polymerization of N-isopropylacrylamide (NIPAAm) in the presence PEO. The thermal characterizations semi-IPNs were investigated differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and dielectric (DEA). melting temperature (Tm) appeared at around 60°C using DSC. DEA was employed to ascertain glass transition (Tg) determine activation energy (Ea) semi-IPNs. From results DEA, exhibited one Tg indicating phase separation semi-IPN, Tgs observed with increasing PNIPAAm content. decomposition semi-IPNa TGA 370°C. © 2003 Wiley Periodicals, Inc.
