摘要：

Based on the lotus effect principle, polyvinylidene fluoride(PVDF) solution was used to construct the microstructure under certain preparation conditions, and the nanostructure was established by plasma enhancing chemical bath deposition. The structural morphology and hydrophobicity were explored by scanning electronic microscopy, atomic force microscopy, and contact angle measuring meter. The experimental results show that PVDF can form smooth microreliefs with diameter about 8 μm on the coating surface, and the water contact angle of PVDF film is 88°. The network nanostructure is constructed by chemical bath deposition(CBD) method, the contact angle and the sliding angle on this surface are 157° and 4°, respectively. Meanwhile, the nanostructure similar to bird claw is constructed by chemical vapor deposition(CVD) method, the contact angle and the sliding angle on this surface are 155° and 4°, respectively. Self-cleaning test shows that the PVDF film prepared by both CBD and CVD method has excellent self-cleaning property.
