Secondly, according to the construction and characteristic of the N-isopropylacrylamide and the temperature-sensitivity of PNIPA hydrogel, Pdualistic hydrogel was synthesized by microwave low temperature plasma. The effects of the factors on the swelling characteristic of P dualistic hydrogel, such as treatment time and power of plasma, concentrations of crosslinking agent and total monomers, proportion of AMPS, polymerizing temperature etc, was discussed in detail. The three dimensions structure , thermostability , reversional volume , swelling/deswelling kinetics, temperature-sensitivity and pH-sensitivity of the hydrogel were also investigated. The optimal synthesizing technics of P dualistic hydrogel initiated by microwave low temperature plasma was confirmed.
