Since biofouling challenges negatively influence the marine and transportation industries, developing effective antifouling materials have attracted extensive concern. A tyrosine-based antifouling phenolic resin (TPP resin) was synthesized using tyrosine as a natural phenol source. TPP exhibited shell-like surface morphology with micro-ripples and excellent anti-adhesion properties against bacteria and diatom. The micro-ripples surface might be caused by the strong hydrogen bonding or ionic interaction among tyrosine units resulting in microphase separation during the curing process. Tyrosine content in TPP resin has a great influence on the surface properties, morphology and antifouling characteristics. The higher the tyrosine content, the higher is the surface hydrophilicity, the denser and more regular is the micro-ripples morphology, and the stronger is the antifouling performance. TPP-60 % exhibited the best antifouling performance. Combination of the surface hydrophilicity and regular micro-ripples surface morphology afford TPP excellent antifouling performance. TPP resins offer a broad prospect for developing phenolic resin in the antifouling field.
由于生物污垢挑战对海洋和运输行业产生负面影响，因此开发有效的防污材料引起了广泛关注。本研究以酪氨酸为天然酚源合成了一种酪氨酸基防污酚醛树脂（TPP 树脂）。TPP 呈现出贝壳状表面形态，具有微观波纹和优异的抗细菌和硅藻附着性能。微观波纹表面可能是由于酪氨酸单元之间的强氢键或离子相互作用导致在固化过程中发生微相分离。TPP 树脂中的酪氨酸含量对表面性能、形态和防污特性有很大影响。酪氨酸含量越高，表面亲水性越高，微观波纹形态越密集、越规则，防污性能越强。TPP-60%表现出最佳的防污性能。表面亲水性和规则微观波纹表面形态的结合为 TPP 提供了优异的防污性能。TPP 树脂为开发防污领域的酚醛树脂提供了广阔的前景。
