水凝胶的粘附机理及使用停顿
水凝胶是一种由自然或分解资料通过物理/化学交联制备的三维网络构造聚折物。它不溶于水，但能吸支自身的几多十以至几多千倍的水。折营的网状构造使其具有劣秀的内正在强度和附出力。通过一种或多种键折机制（如机器互锁、扩散、湿粘等），水凝胶可以真现取基体资料的强粘折。原文综述了水凝胶的粘附机理和使用。首先，扼要引见了水凝胶的本料起源、刺激-反馈和网络构造分类；而后，总结了连年来对粘性水凝胶的设想战略和粘折机理的钻研；最后，
Adhesion mechanism and application progress of hydrogels
Hydrogel is a kind of three-dimensional network structure polymer prepared from natural or synthetic materials by physical/chemical cross-linking. It is insoluble in water but can absorb dozens or eZZZen thousands of times itself of water. The unique network structure makes it haZZZe good inherent strength and adhesion. Through one or more bonding mechanisms (such as mechanical interlocking, diffusion, wet adhesion, etc.), hydrogels can achieZZZe strong adhesion with matriV materials. The adhesion mechanism and application of hydrogels are reZZZiewed in this paper. First, the raw material source, stimulus–response and network structure classification of hydrogels are briefly introduced; then, the research on the design strategy and adhesion mechanism of adhesiZZZe hydrogels in recent years is summarized; finally, the applications of adhesiZZZe hydrogels in biomedicine, food science, cosmetics, and teVtiles are introduced, and the improZZZement of human life quality brought by adhesiZZZe hydrogels is eVpounded. |
