摘要

Abstract

In this paper

we report on the comprehensive alcohol-/ion-responsive properties of a smart copolymer poly(Nisopropylacrylamide-co-benzo-18-crown-6-acrylamide) (P(NIPAM-co-BCAm)). The orthogonal design method is adopted for experimental design. The experimental results show that alcohol can trigger the shrinking and Ba

can induce the swelling of the P(NIPAM-co-BCAm) copolymer. According to the phase transition temperature (LCST) change results of the copolymer

the influence of variables on the LCST changes weakens in the following order: alcohol concentration N alcohol species N metal ion species N BCAm concentration N ion concentration. The larger the alcohol concentration and the larger the molecular size of alcohols

the lower the LCST value; on the contrary

the more the BCAm content in the copolymer or the larger the BCAm/ion complex stability constant (lgK) or the larger the ion concentration is

the higher the LCST value. For a P(NIPAM-co-BCAm) copolymerwith a fixed BCAmcontent

a binary function of ion concentration and lgK of BCAm/ion is developed to precisely predict the LCST values of the copolymer in different metal ion solutions. The results provide valuable information for fabricating artifici

al biomimetic G-protein-gated inwardly rectifying potassium (GIRK) channels that are activated by alcohol and inhibited by Ba
