A Novel Structure Having Linear Poly(N-Isopropylacrylamide) Chains with Rapid Response to Temperature Changes
In this article, a novel structure poly(N-isopropylacrylamide) (PNIPAM) hydrogel, which is featured with both ends of linear PNIPAM chains being grafted onto semicircular and cross-linked PNIPAM chains, has been successfully prepared in a three-step process by a method of sequential synthesis for the first time. The proposed hydrogel displays faster and hydration/dehydration dynamic response to temperature cycling owing to linear PNIPAM chains to form big-hole structure. This work may be highly attractive for targeting drug delivery systems, polymeric machinery, and sensors and so on.
