中文摘要:
      目的 研究包装透明超疏水聚乙烯(PE)薄膜的制备方法及其性能。方法 以纳米二氧化硅和无水乙醇为原料,将纳米二氧化硅溶于无水乙醇制得二氧化硅半透明溶液,采用浸渍提拉法将PE 膜在二氧化硅溶液中浸泡数分钟后提拉取出并自然干燥,然后用扫描电子显微镜、接触角测量仪、透光率雾度测定仪测量膜表面的性能,并进行研究分析,用污水浸泡样品数天后测量其抗污性。结果 成功制备了透明超疏水PE 薄膜,其表面与水的接触角高达(171±2)?,滚动角低至1?。当纳米二氧化硅的质量浓度为10 mg/mL时,其薄膜表面表现出了优异的透明性、防水性和抗污染自清洁性。结论 采用简易方法制备了透明超疏水聚乙烯塑料薄膜,提高了聚乙烯膜超疏水自清洁的性能,大大增强了聚乙烯膜在包装领域的应用前景。
英文摘要:
      The work aims to study the preparation and properties of transparent superhydrophobic polyethylene (PE) packaging films. With nanosilica and absolute ethyl alcohol as raw material, nanosilica was dissolved into the absolute ethyl alcohol to prepare semi-transparent silica solution. PE film was dip-coated into silica solution for a few minutes before pulling out for natural drying. The performance of the film surface was measured and analyzed by scanning electron microscope, contact angle measuring instrument, light transmittance measurement instrument, and the anti-pollution of the sample was measured after the sample was soaked in sewage for a few days. Transparent superhydrophobic PE film was successfully prepared. The contact angle between its surface and water was as high as (171±2)° and the rolling angle was as low as 1°. The excellent transparency, water resistance and anti-pollution and self-cleaning property were showed in the film surface when the concentration of nanosilica was 10 mg/mL. An easy and effective method used to prepare transparent superhydrophobic PE films has improved the superhydrophobic and self-cleaning property of PE film, which greatly enhances the application prospect of PE films in packaging field.
