中文摘要：COVID-19大流行突出了对市场多样化和个人防护装备(PPE)替代材料的需求。纸具有可调阻隔性能的高涂布性和灵活的生产工艺，使其成为聚烯烃衍生PPE材料的潜在替代品。将漂白纸和新闻纸与不同厚度的聚乙烯（PE）涂层层压，并对其作为医护人员和COVID-19患者的医疗服的潜在用途进行了研究。研究表明，较厚的PE层压改善了涂层的均匀性和耐水蒸气性。涂布16GSM PE涂层后，49GSM漂白纸具有较高的拉伸强度和接缝强度，以及较低的水蒸气透过率（WVTR）。Phi-X174噬菌体测试显示，纸层压15 GSM涂层可阻碍病毒渗透。可见，PE层压纸是一种很有前景的低成本病毒防护服材料。
外文摘要：The COVID-19 pandemic has highlighted the need for diversity in the market and alternative materials for personal protective equipment (PPE). Paper has high coatability for tunable barrier performance, and an agile production process, making it a potential substitute for polyolefin-derived PPE materials. Bleached and newsprint papers were laminated with polyethylene (PE) coatings of different thicknesses, and characterised for their potential use as medical gowns for healthcare workers and COVID-19 patients. Thicker PE lamination improved coating homogeneity and water vapour resistance. 49 GSM bleached paper with 16 GSM PE coating showed high tensile and seam strength, and low water vapour transmission rate (WVTR). Phi-X174 bacteriophage testing revealed that paper laminated with 15 GSM coating hinders virus penetration. This research demonstrates that PE laminated paper is a promising material for low cost viral protective gowns.
