| 中文摘要: |
| 本研究以微晶纤维素为原料，通过亲核取代反应合成了肉豆蔻纤维素酸酯（CME），利用激光雕刻图案和聚二甲基硅氧烷（PDMS）预固化协同的界面图案锚定策略，制备出一种强界面结合的纤维素基疏水表面，并通过调控界面图案结构，探究了纤维素疏水表面的界面结合机制，以期为解决纤维素涂层与低表面能基材间界面结合稳定性不足的问题提供有效方案。结果表明，通过界面图案锚定，纤维素功能涂层与氟化乙烯丙烯共聚物（FEP）基材之间剥离强度高达58.5 N/m，且该表面展现出优异的耐磨性和耐受性，在250次剥离循环和90 cm砂纸磨损后，表面疏水性依然稳定。 |
| Abstract: |
| Using microcrystalline cellulose as the raw material， this study synthesized myristoyl cellulose ester (CME) via nucleophilic substitution reaction. Furthermore， a cellulose-based hydrophobic surface with strong interfacial adhesion was fabricated by employing a synergistic interfacial pattern anchoring strategy combining laser-engraved patterning and polydimethylsiloxane (PDMS) pre-curing. In order to provide 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. |
