| Abstract: | A new type of dualistic intelligent hydrogel,P(AMPS/NIPA) hydrogel,was synthesized from NIPA and AMPS by microwave plasma polymerization and the characteristics of the hydrogel were studied.Firstly,the affecting factors such as treatment power and treatment time of plasma are discussed in detail.Secondly,temperature-sensitivity,swelling/shrinking kinetics and pH-sensitivity of the P(AMPS/NIPA) hydrogel were investigated respectively. Then the composition and the three dimensional crosslinked net structure were characterized.The results show that the prepared P(AMPS/NIPA) hydrogel has a large swelling ratio,good temperature-sensitivity,pH-sensitivity and rapid responding speed. |
