Paper Title:
Preparation and Properties of a Novel Azobenzene-Based Polyacrylamide Hydrogels with Photoresponse
  Abstract

A novel photoresponsive hydrogels of poly(acrylamide-co-acrylamido azobenzene) (p(AAm-co-AAAB)) consisting of acrylamide (AAm) and acrylamido azobenzene (AAAB) was prepared via a free-radical copolymerization route by using 2,2’-azobisisobutyronitrile (AIBN) as initiator, and N,N-methylene bisacrylamide (MBAA) as a crosslinking agent. The photoresponsive behaviors were studied. The variations of volume and swelling ratio of p(AAm-co-AAAB) hydrogels under UV or visible light irradiation indicated that PAAm hydrogels have no UV light sensitivity, but with the increase of the time of UV irradiation, the volume and swelling ratio of p(AAm-co-AAAB) hydrogels decreased, and then increased with the extending of the time after UV irradiation for the isomerization. The results disclosed that the copolymer hydrogels possess good photoresponsive property to UV irradiation, and the photoresponsive behavior is reversible with the transformation between UV and visible light irradiation.
