A pH responsive opal N-isopropylacrylamide/acrylic acid copolymerized hydrogel was prepared as an example. The ordered structure and response to pH were investigated. Through the sol-gel process of tetrabutyl titanate, opal titania was obtained with the opal hydrogel template. %K hydrogels %K templates %K ordered %K colloids %K structures %U http://link.springer.com/article/10.1007/BF03184058
