Abstract

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.

有机和无机混合超疏水涂层增强了竹子的表面特性

作为一种具有巨大潜力的吸碳和生物降解材料，竹子具有广阔的应用前景。然而，由于竹子天然结构和化学成分的缺陷，如表面亲水性和淀粉等营养物质的存在，给应用过程带来了问题，阻碍了竹子的进一步利用。我们利用聚二甲基硅烷和 HMDS-PDA-TiO2 纳米粒子，通过共价键和氢键的相互作用，在竹子表面自组装了一种有机-无机混合超疏水涂层。涂层竹材具有超疏水性、自洁能力和更好的物理化学耐候性。此外，由于在竹子表面构建了光电催化等环境，竹子还具有优异的防霉性和耐老化性。通过这种既美观又环保的方法，可以开发出具有上述优异性能和新功能的新型竹材料，为竹材的高值化利用提供了一条潜在的产业途径。

期刊介绍： Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
