主　　题：Transparent hydrogel Semi-IPN hydrogel Acrylic acid Freeze-thaw technique Electroactive behaviour 

摘      要：In this paper,poly(vinyl alcohol)-poly(acrylic acid)based transparent semi-interpenetrating network(semi-IPN)hydrogels were synthesized by using a solvent mixture of dimethyl sulfoxide and deionized water via free radical polymerization and subsequent freeze-thaw *** formation of the semi-IPN hydrogels was conformed from FT-IR *** acrylic acid concentration effect on the hydrogels was investigated in terms of transparency,crystalline structure and thermal stability by using UV-visible spectroscopy,X-ray diffraction and thermogravimetric *** behaviours of the semi-IPNPAP hydrogels were studied in deionized water and different pH *** compression and electroactive behaviour was tested in fully hydrated stage by using compression test and by applying electrical *** hydrogels showed displacements under the applying voltage and detailed experiment is illustrated.
