中文摘要	a novel approach is presented for fabricating the thermo-responsive poly(n-isopropylacrylamide) hydrogels (tphs) using starch-based nanospheres with derivable allyl groups as nanoscale crosslinkers. the obtained hydrogels possess an extremely high mechanical strength and a remarkably rapid shrinking time, which is much shorter than the time it will take for a conventional hydrogel (ch). moreover, the effects of the crosslink density on the swelling, deswelling, and mechanical properties are also systematically studied. the results show that tphs can sustain strength two hundred times more than the ch, and the characteristic time of deswelling is almost eight times shorter than that of ch. these excellent properties of the tph gels can be attributed to their special microstructure and the even distribution of the starch-based nanospheres in the hydrogel network.
