The current research focuses on tailoring silica nanoparticles (SiO₂NPs) with comb-like poly(dodecyl methacrylate) (PDMA) brushes and tuning coating parameters based on roller coating process for confining surface morphology towards hydrophobic and superhydrophobic including water-repellent surface. Electron beam (EB) induced a simultaneous “graft-from” polymerization of DMA monomer onto vinyl modified SiO₂NPs (SiO₂NPs-V) was established in an inventive castor oil/ethanol mixed solvent. Functional surface chemistry of SiO₂NPs and nanorough surface topography controlled by NPs content and coating thickness mainly influences the hydrophobic/superhydrophobic, water-repellent, and water absorption properties including gloss values, whiteness and yellowness index of coated papers. The papers coated with SiO₂NPs-V-PDMA/PVA of 6–10 wt% with the thickness of ~10–14 μm exhibited matt surface and provided superhydrophobic and water-repellent properties. The coated paper has a desirable and stable water contact angle of 152°, low droplet adhesion with lower dynamic tilting angle (<5°), and 5.3-folds reduced water absorption. Our investigation provides compelling evidence that the SiO₂NPs-V-PDMA obtained from EB modification and the developed coating formula for roller-based coating process are realistic approaches for hydrophobic/superhydrophobic coatings and printing inks for paper-based industries.

目前的研究重点是用梳状聚（甲基丙烯酸十二烷基酯）（PDMA）刷定制二氧化硅纳米粒子（SiO ₂ NPs），并基于辊涂工艺调整涂层参数，以将表面形态限制为疏水和超疏水，包括拒水表面。在本发明的蓖麻油/乙醇混合溶剂中，电子束（EB）诱导DMA单体同时“接枝”聚合到乙烯基改性的SiO ₂ NPs（SiO ₂ NPs-V）上。SiO _{2 的}功能表面化学纳米颗粒和纳米粗糙表面形貌受纳米颗粒含量和涂层厚度控制，主要影响涂层纸的疏水/超疏水、拒水和吸水性能，包括光泽值、白度和黄度指数。涂有6-10 wt% SiO ₂ NPs-V-PDMA/PVA 且厚度约为 10-14 μm的纸表现出亚光表面，并提供超疏水和防水性能。涂布纸具有理想且稳定的水接触角为 152°，具有较低的动态倾斜角 (<5°) 的低液滴附着力，以及 5.3 倍的吸水率降低。我们的调查提供了令人信服的证据，证明 SiO ₂从 EB 改性获得的 NPs-V-PDMA 和为辊基涂布工艺开发的涂层配方是用于纸基工业的疏水/超疏水涂层和印刷油墨的现实方法。
