Abstract
A hydrochromic polydiacetylene polymer patch and a method of manufacturing the same are provided. The hydrochromic polymer patch comprises a polymer matrix; and polydiacetylene present in the polymer matrix. The polydiacetylene has an ionic functional group in the repeating unit thereof. The ionic functional group is R−M+ or R+X−. R− is a carboxylate anion, M+ is an alkali metal cation, and R+ is a quaternary ammonium group, and X− is F−, Cl−, Br−, I−, PF6−, BF4−, bis(trifluoromethane)sulfonimide (Tf2N−), trifluoromethanesulfonate (TfO−), SCN−, or CH3COO−.
