The phase transition temperature increases and the transition ranges tends to be broad when PNIPA brushes were substituted with P or P(NIPA-co-NVP) brushes obtained by the copolymerization of NIPA with AA and NVP, respectively. However, the phase transition is not obvious if adding excessive hydrophilic comonomer.

结果表明，纯PNIPA刷的相变温度在29℃~33℃之间，通过共聚所得的单一P或P(NIPA-co-NVP)刷均使相转变温度提高，转变区域拓宽，当亲水性共单体的量过多时会导致相变过程不明显。

The anisotropy inverted spectra will be determine, when the temperature reaches and goes beyond the temperature of phase transition for the NNPA and NIPA hydrogels that exhibit a LCST phase behaviors. The network is collapsed and the hydrated Cu ion is bound by network chains.

对于具有LCST相行为的NNPA 和NIPA水凝胶，当温度达到并超过其相转变温度时，即可测得其Cu自旋探针各向异性的ESR倒置谱，这种倒置谱是由于凝胶相变后，网格塌陷，网络缠裹水化Cu离子的结果。

It is to say that the patch of RAFT agent on the hairy chains.PS particles with the shell of copolymer of styrene and vinylbenzyl chloride were prepared by similar seeded and starved addition processes. RAFT agent with carboxyl end-group attached on the shell surface of PS particles by group reaction. Adding NIPA and photo-initiator into the continuous phase of polymerization system, hairy PNIPA were obtained.

最后，以表面负载一层乙烯基苄氯的亚微米级单分散聚苯乙烯微球为基质，将水溶性RAFT试剂与聚苯乙烯微球表面的官能团反应以负载到其表面，再在连续相中直接引入NIPA和光引发剂，RAFT聚合得到PNIPA毛发。

Finally, the grafting polymerization of textile materials initiated by microwave low temperature plasma was conducted. Knitted cotton fabric was grafted by AMPS first, then knitted cotton and terylene/cotton fabrics were grafted with AMPS/NIPA dualistic monomers respectively. By means of grafting polymerization, the P dualisticintelligent hydrogel was added to textile.The influences of the factors on add-on, such as treatment time and power of plasma, concentrations of crosslinking agent and total monomers, proportion of AMPS, polymerizing temperature and time etc, was studied fully. The optimal conditions of grafting polymerization initiated by microwave low temperature plasma were determined by orthogonal design, variance analysis and mathematical statistics method so as to analyze the main influencing factors. Then swelling/deswelling kinetics, temperature-sensitivity and pH-sensitivity of grafted textile were studied. The performance indexes of hydrostatic pressure, moisture permeability and bursting strength of the knitted cotton and terylene/cotton fabrics before and after grafting were compared and evaluated synthetically.
