Integration of hydrogel with functional nanoparticles using hydrophobic comb-like polymers as an adhesive layer

Abstract

Surface functionalization of hydrogels are strategies that can partly endow hydrogels with desired properties, while keeping the intrinsic hydrophilicity and biocompatibility of hydrogel network intact. Here we report a ubiquitous strategy to functionalize the surfaces of hydrogel with functional nanoparticles. By taking advantage of quaternization reactions that confined at hydrogel/oil immiscible interface, comb-like polymers are covalent bonding to the surfaces of hydrogel. The comb-like polymers on hydrogel surface formed a hydrophobic modified layer, which can further work as an adhesive layer and contribute to the integration of hydrogel with functional nanoparticles. For example, the integration of hydrogel with superhydrophobic silica nanoparticles endows the hydrogels with controllable surface wettability and water adhesion. Meanwhile, a hydrogel-based supercapacitor is also prepared through the integration of hydrogel with conductive polyaniline nanoparticles. Moreover, the universality of current approach to different hydrogel systems is confirmed. Consequently, it is supposed that this work provides a general strategy for the fabrication of multifunctional hydrogel.
