Study on the Super Hydrophobic Property of Bamboo by Gas Phase Nano SiO2 Modification

Abstract

This paper is to explore a simple and effective experimental method to transform the bamboo’s hydrophobic property that enables them to achieve super hydrophobic effect. Soaking the experimental materials in nano-silicon dioxide solution is to prepare the super hydrophobic material. The particle size of silicon dioxide, contact angle of the transformed material, scanning electron microscope and energy spectrum were tested. The results show that the gas phrase nano-silicon dioxide solution is double microscopic particles which are advantageous to form the super hydrophobic structure. After transforming the property, both the contact angle of the outboard and inboard of bamboo can reach 150 degree or above, after transforming, there forms a super-hydrophobic thin film on the surface of bamboo material. The technology of forming a super hydrophobic structure on the surface of the gas phase nano-silicon dioxide is simple. This experiment is referentially meaningful in production.
