Preparation of glass‐fiber membranes grafted with poly(NIPAAm containing triphenylmethane leucocyanide) and permeation of solutes through the membranes

Glass‐fiber membranes (GF membranes) grafted with poly(N‐isopropylacrylamide containing triphenylmethane leucocyanide) [poly(NIPAAm–LeCN)] were prepared. Ultraviolet irradiation of the GF membranes with poly(NIPAAm–LeCN) induced a change in the phase‐transition temperature of the poly(NIPAAm) segments. The changes in both the phase‐transition temperature of the poly(NIPAAm) segments and the permeation rate of solutes are discussed in relation to the dissociation of LeCN molecules.
