A smart paper that provided sustained release of benzalkonium chloride (BKC) at a set temperature was prepared. Filter paper impregnated with an oil‐in‐water emulsion containing BKC, methyl methacrylate monomer, ethylene diamine, and 2,2‐azobis(2,4‐dimethylvaleronitrile) was immersed in a cyclohexane solution of terephthaloyl chloride. A polyamide film containing the BKC MIP was formed on the paper surface via an interfacial polymerization reaction. Dimethlydistearylammonium bromide (DDB) was then coated over the polyamide film. The interfacial polymerization reaction eliminated the need for preparation of microcapsules of BKC or coating of the paper with a binder, which are methods commonly used for preparation of smart papers. Release of BKC from the paper was studied, and the temperature responses obtained with the DDB coating were evaluated. The smart paper with the BKC MIP and DDB coating showed sustained release of BKC, and this function was obtained in response to a certain temperature. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.
