Abstract

Here, we designed a surface-grafted hydrogel (SG gel) that exhibits thermoresponsive changes in surface properties. Quantitative measurements using a self-made device showed that the adhesive strength between the SG gel surface and a Bakelite plate due to hydrophobic interaction changed significantly with temperature.

摘要

在此，我们设计了一种表面接枝水凝胶（SG凝胶），其表面性质呈现热响应变化。使用自制装置进行的定量测量表明，由于疏水相互作用，SG凝胶表面与酚醛树脂板之间的粘附强度随温度显著变化。
