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.
