AI Technical Summary
Existing PE films have poor oxygen barrier properties, especially in high humidity environments where their performance deteriorates rapidly. Furthermore, existing modification methods present safety risks and complex processes.
PE films are treated with modified polyvinyl alcohol coating solution and zinc stearate solution. The coating solution is composed of polyvinyl alcohol, tannic acid and nano-hydroxyapatite. It enhances the barrier layer by forming a multi-hydrogen bond network and nano-functional fillers, and combines with zinc stearate to form a physically hydrophobic layer, thereby improving the barrier performance against oxygen and water vapor.
It significantly improves the oxygen and water vapor barrier properties of PE film in high humidity environments, enhances the density and stability of the barrier layer, and improves mechanical properties.
