Abstract

Conventional hydrophobic paper coatings face persistent trade-offs among performance, sustainability, and cost. Herein, cetyltrimethylammonium bromide (CTAB)-modified acrylic copolymer coating via micellar copolymerization of acrylic acid (AA) and lauryl methacrylate (LMA) was synthesized and applied to paper via scraper coating. The CTAB served a triple role, functioning as an emulsifier, a hydrophobic modifier, and an antimicrobial agent of the coating. With a 3-layer application, the coated paper achieved stable hydrophobicity (water contact angle ≈120°), excellent oil resistance (kit rating 10), high tensile strength (∼26.7 MPa), reduced water vapor permeability to 71 g/ (m²·24 h), and exceptional antibacterial activity against E. coli and S. aureus. The coated paper demonstrated suitability for hot/cold beverage packaging (leakage-free at 80 °C for 24 h) and water-resistant writing protection (waterproof ink retention). Furthermore, discarded coated paper was upcycled via alkaline treatment into a superabsorbent material (water absorption about 2172 %) suitable for soil moisture retention. This CTAB-driven design synergistically integrated hydrophobicity, oil resistance, antibacterial functionality, and circularity, offering a scalable solution for sustainable packaging.

十六烷基三甲基溴化铵改性丙烯酸共聚物涂料制备可持续包装用疏水纸

传统的疏水性纸涂料在性能、可持续性和成本之间面临着持久的权衡。本文以丙烯酸（AA）与甲基丙烯酸月桂酯（LMA）胶束共聚为原料，合成了十六烷基三甲基溴化铵（CTAB）改性丙烯酸共聚物涂料，并通过刮板涂料应用于纸张。CTAB具有乳化剂、疏水改性剂和抗菌剂的三重作用。通过3层涂布，该涂布纸具有稳定的疏水性（水接触角≈120°），优异的耐油性（kit rating 10），高拉伸强度（~ 26.7 MPa），水蒸气渗透率降至71 g/ (m2·24 h)，对大肠杆菌和金黄色葡萄球菌具有优异的抗菌活性。涂布纸证明适合热/冷饮料包装（在80°C下24小时无泄漏）和防水书写保护（防水油墨保留）。此外，废弃铜版纸经碱性处理后可再生为高吸水性材料（吸水率约为2172%），适合土壤保持水分。这种ctab驱动的设计协同集成了疏水性，耐油性，抗菌功能和循环性，为可持续包装提供了可扩展的解决方案。

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
