摘要
纤维素基材料具有原料来源广泛、可生物降解和优异的生物相容性等特点,且其本身的粗糙结构对其表面浸润性的改性具有一定的优势。基于浸润性的概念和改性原理,总结了纤维素基材料在疏水、超疏水和亲水疏油三个改性方向上的表面浸润控制技术,重点阐述纤维素基材料的表面超疏水改性技术。
As a green, renewable and biodegradable material, cellulose-based materials have excellent biocompatibility and are a widely available resource. Their rough structures have an advantage for modification of surface wettability. In this paper, the authors reviewed concepts and modification principles of wettability, summarized technologies of controlling surface wettability in hydrophobicity, superhydrophobicity and hydrophilicity-hydrophobicity directions as well as focused on surface superhydrophobicity modification technology of cellulose-based materials.
