摘      要：In this study,hydrogels of P(NIPA-co-NVP)/clay were synthesized byγ-ray *** thermo-sensitive hydrogels were made under different experimental conditions such as dose,monomer ratio,and con- tent of clay.X-ray diffraction shows that the layer distance between Na-clays is changed from 1.6 to 2.7 nm because Na-clay pieces can be intercalated or exfoliated by HTMAB,and that between P(NIPA-co-NVP)/clay pieces is 3.4 nm. The swelling property tests show that the LCST of P(NIPA-co-NVP) is higher than *** the increase of NVP content,LCST is *** the ratio of NIPA/NVP is 95/5,hydrogel shows the best swelling property and LCST is 37℃.LCST of P(NIPA-co-NVP)/clay hydrogel is not changed,but the strength and swelling properties are better.
