Abstract

Hydrogel-based soft materials have attracted significant attention in various fields due to their high water content, good biocompatibility, and variable mechanical strength. However, due to the hydrophilic properties of hydrogel networks, most of the hydrogel-based soft materials are easy to swell in water and have monotonous surface wettability. Here, taking advantage of the intrinsic hydrophobicity of siloxane, novel heteronetwork organohydrogels were synthesized by covalently integrating reactive siloxane monomers into the hydrophilic hydrogel networks via emulsion polymerization. The surface of the heteronetwork organohydrogels exhibited adaptive wettability owing to the rearrangement of the surface chemistry induced by varying solvent conditions. Moreover, the heterogeneous networks endowed organohydrogels with excellent anti-swelling abilities in water or oil (n-heptanes). The potential application of the prepared organohydrogels in the field of oil/water separation was also preliminarily explored. The idea and method of integrating polysiloxane into hydrogels in this study might provide a new insight to develop high-performance polysiloxane-based heteronetwork gel materials.

基于聚丙烯酰胺/聚硅氧烷乳液的异构网实现具有自适应表面润湿性的有机水凝胶

水凝胶基软材料因其高含水量、良好的生物相容性和可变的机械强度而在各个领域备受关注。然而，由于水凝胶网络的亲水性，大多数水凝胶基软材料在水中容易膨胀，表面润湿性单一。本文利用硅氧烷固有的疏水性，通过乳液聚合将活性硅氧烷单体共价结合到亲水性水凝胶网络中，合成了新型异网络有机水凝胶。由于不同溶剂条件下表面化学成分的重新排列，异构网络有机水凝胶的表面呈现出自适应润湿性。此外，异构网络还赋予了有机水凝胶在水或油（正庚烷）中卓越的抗溶胀能力。此外，还初步探讨了制备的有机水凝胶在油/水分离领域的潜在应用。本研究中将聚硅氧烷整合到水凝胶中的思路和方法可能会为开发高性能的聚硅氧烷基异质网络凝胶材料提供新的思路。
