高耐久纤维素疏水表面构建及其界面强化机制研究
Preparation of Highly Robust Cellulose Hydrophobic Surfaces and Research on Their Interfacial Strengthening Mechanisms
摘要
Abstract
Using microcrystalline cellulose as the raw material,this study synthesized myristoyl cellulose ester(CME)via nucleophilic substi-tution reaction.Furthermore,a cellulose-based hydrophobic surface with strong interfacial adhesion was fabricated by employing a synergis-tic interfacial pattern anchoring strategy combining laser-engraved patterning and polydimethylsiloxane(PDMS)pre-curing.In order to pro-vide an effective solution to address the insufficient interfacial bonding stability between cellulose coatings and low surface energy substrates.The results showed that,through interfacial pattern anchoring,the peel strength between the cellulose functional coating and the fluorinated ethylene propylene copolymer(FEP)substrate reached 58.5 N/m.The surface also exhibited excellent abrasion resistance and durability,with the surface hydrophobicity remaining stable after 250 peel cycles and 90 cm sandpaper abrasion.关键词
