Organic and inorganic hybrid superhydrophobic coating enhances the surface properties of bamboo

As a carbon absorbing and biodegradable material with great potential, bamboo has a bright application prospect. However, due to the defects in the natural structure and chemical composition of bamboo such as surface hydrophilicity and the presence of nutrients such as starch, it causes problems in the application process and hinders the further utilization of bamboo. We use polydimethylsilane and HMDS-PDA-TiO₂ nanoparticles to self-assemble an organic-inorganic hybrid superhydrophobic coating on the surface of bamboo through the interaction of covalent and hydrogen bonds. The coated bamboo possesses superhydrophobicity, self-cleaning ability and improved physicochemical weathering resistance. In addition, due to the construction of photoelectrocatalytic and other environments on the surface, bamboo has excellent mold resistance and aging resistance. Through this aesthetically pleasing and environmentally friendly approach, a new type of bamboo material with the aforementioned excellent properties and new functions can be developed, providing a potential industrial pathway for the high-value utilization of bamboo.
