Polyvinyl alcohol (PVA) based anti-fogging layer has been successfully developed with an impressive long shelf-life by remarkably increasing the wettability of low-density polyethylene (LDPE) films for agricultural greenhouses application. The plasma treatment of LDPE films was initially implemented, followed by the solution casting method. Tris-buffered saline (TBS) was added for enhancing the interaction between the anti-fogging agents and PVA polymer. Silica nanoparticles were used to enhance the stability of the layer. Time-domain NMR clarified the homogeneous silica distributed. The results show an increase in bound water fractions promotes silica distribution homogeneously. Also, obtained films become super-hydrophilic, having a contact angle less than 2° without water droplets formation under the hot fog test, for 1 month at 60 °C. The use of a unique PVA-TBS/Surfactant-SiO₂ based anti-fogging agent shows excellent performance of LDPE films, which provides a key in solving the problem of fogging for agriculture greenhouses.

通过显着提高用于农业温室应用的低密度聚乙烯 (LDPE) 薄膜的润湿性，已成功开发出基于聚乙烯醇 (PVA) 的防雾层，并具有令人印象深刻的长保质期。LDPE 薄膜的等离子体处理最初实施，然后是溶液流延方法。添加 Tris 缓冲盐水 (TBS) 以增强防雾剂与 PVA 聚合物之间的相互作用。二氧化硅纳米粒子用于增强层的稳定性。时域 NMR 澄清了均匀的二氧化硅分布。结果显示结合水分数的增加促进了二氧化硅的均匀分布。此外，获得的薄膜变得超亲水，在 60°C 下保持 1 个月，在热雾测试下接触角小于 2°，不会形成水滴。₂型防雾剂显示出LDPE薄膜优异的性能，为解决农业大棚雾化问题提供了关键。
