The Effects of Zinc Oxide/Silicon Dioxide Composite Coating on Surface Wettability and the Mechanical Properties of Paper Mulching Film

In order to improve the hydrophobic and mechanical properties of paper mulch film, ZnO/SiO2 composite coated film was prepared with a brush coating method. Hydrophobicity durability original were measured by static contact angle torsion tests, two kinds films tensile tear tests at different temperatures. The characterized their micro-morphology surface element distribution. results show that reaches 161.46°, can still reach 153.15° after 80 cycles, which shows good superhydrophobic durability. Compared are also improved some extent. Combined micro-morphology, it is found fills pores between fibers in promotes adhesion fibers, thus improving hydrophobicity, durability, film.
