Study on Anti-Fog Films of Polyethylene Modified with Inorganic Micrometer Diatomite

Abstract:

Anti-fog films of low density polyethylene (LDPE) modified with micrometer diatomite were prepared by a process of blow molding. Through examination of antifogging property of the film added the anti-fog agents, the modification effectiveness of inorganic micrometer diatomite and the influence of different treating agents were studied with Fourier transform infrared spectrometer (FTIR), mechanical properties, and antifogging performances. The results indicate that the anti-fog property of the film can be improved by premixing inorganic micrometer diatomite with the anti-fog agents; the film modified by inorganic micrometer diatomite added surface treatment agent has obviously effectiveness anti-fog properties than that the films modified only by the anti-fog agents. Addition of polyacrylamide can make the anti-fog durability of the films modified by inorganic micrometer diatomite be further prolonged. It was observed that the tensile strength does not show any decrease, however, elongation at break show a massive decreased.
