| titleOfInvention | A kind of preparation method of using geothermal water to construct superhydrophobic layer on bamboo/wood surface |
| abstract | The invention relates to a preparation method for constructing a superhydrophobic layer on the surface of bamboo/wood by utilizing geothermal water. First, the lignin on the bamboo/wood surface is removed by treatment with NaOH solution, so that the hydroxyl group is exposed on the surface layer as much as possible, and then it is immersed in methacrylic acid to shrink After reacting in a glyceride solution, calcium carbonate crystals were finally deposited on the surfaces of bamboo and wood by hydrothermal method, and polydimethylsiloxane, a low surface energy substance, was combined to build an aragonite-type calcium carbonate surface layer with hydrophobic function on the surface of bamboo/wood. Advantages: 1) NaOH solution treatment is used to remove lignin components on the surface of bamboo/wood, so that the hydroxyl groups in bamboo/wood are exposed on the surface as much as possible, which is beneficial to the next reaction. 2) Using GMA as the coupling agent, the epoxy group reacts with the hydroxyl group to make it fixed on the bamboo/wood surface, the carboxyl group and Ca 2+ form a complex, which is controlled by adjusting the complex formed by the carboxyl group and Ca 2+ Growth crystal form and morphology of calcium carbonate. 3) Green environmental protection, good biocompatibility, low production cost and good hydrophobicity. |
