Polyelectrolyte adhesives, either poly[2-(dimethylamino)ethyl methacrylate] or poly(methacrylic acid), functionalized with a surface-active calix[4]resorcinarene were grafted onto silicon wafers. Adhesion studies on these grafted-to brushes using polyelectrolyte hydrogels of opposite charge showed that it is the calix[4]resorcinarene, rather than adsorption of polyelectrolyte monomers, that adheres the brush to the silicon substrate. The adhesion measured was similar to that measured using polymers grafted from the surface, and was stronger than a control layer of poly(vinyl acetate) under the same test conditions. The limiting factor was determined to be adhesive failure at the hydrogel-brush interface, rather than the brush-silicon interface. Therefore, the adhesion has not been adversely affected by changing from a grafted-from to a grafted-to brush, demonstrating the possibility of a one-pot approach to creating switchable adhesives.

用Calix [4]间苯二甲烯官能化并单层沉积的接枝至聚电解质电刷的粘附性

用表面活性杯[4]-间苯二甲烯官能化的聚电解质粘合剂，即聚[甲基丙烯酸2-（二甲基氨基）乙酯]或聚（甲基丙烯酸），被移植到硅片上。使用带相反电荷的聚电解质水凝胶对这些接枝刷的粘附性研究表明，是杯[4]间苯二甲烯而不是聚电解质单体的吸附将刷粘附到硅基底上。测得的粘附力与使用从表面接枝的聚合物测得的粘附力相似，并且在相同的测试条件下比聚醋酸乙烯酯的对照层更强。确定的限制因素是在水凝胶-刷子界面而不是刷子-硅界面的粘合失败。因此，
