A series of poly(acry1ic acid) (PAA)-poly(viny1 alcohol) (PVA) semiinterpenetrating (SIPN) and interpenetrating (IPN) polymer network membranes were prepared by crosslinking PVA alone or by crosslinking both PVA and PAA. Glutaraldehyde and ethylene glycol were used as crosslinking agents for the PVA
The swelling behavior of interpenetrating polymer networks (IPNs) composed of poly(viny1 alcohol) (PVA) and poly(acry1ic acid) (PAA) in water was studied. The PVA/ PAA IPN gels were prepared by four synthetic methods. The swelling behaviors of these IPNs made by different methods were compared. The
The pH-sensitive photocatalytic system was prepared by embedding TiO 2 into poly(vinyl alcohol)/poly(acrylic acid) hydrogel. Two different type TiO 2 /hydrogel composites, such as matrix and nanofiber, were prepared to investigate the morphological effects on the photocatalytic activity. TiO 2 was d
## SYNOPSIS T h e swelling behavior of novel pH-and temperature-sensitive interpenetrating polymer networks (IPNs) composed of poly(viny1 alcohol) (PVA) and poly(acry1ic acid) (PAAc) in water was investigated. The PVA/PAAc IPN hydrogels were synthesized by UV irradiation, followed by a repetitive
