【摘要】：采用软模板法和自模板法分别制备了Cu_2O空心球,探索了不同制备方法下反应条件对Cu_2O空心球形貌及性能的影响,研究了以其作为防污剂制备的涂层防海洋污损生物的防污性能。通过X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和抑菌测试等手段表征和探讨了Cu_2O空心球的抑菌性能。结果表明:用软模板法得到表面光滑、结晶度高的Cu_2O空心球;用自模板法制备得到由纳米粒子组成的开口空心微球。在抑菌试验中,2种空心球浊液浓度为50μg/m L时,抑菌作用均可以达到95%以上,抑菌效果好。将2种Cu_2O空心球作为防污剂与含氟嵌段共聚树脂SBF改性树脂混合,得到2种杂化防污涂层。通过SEM进行表征,在抗藻类附着试验中,表面基本没有藻类附着,具有良好的防污性能。在浸泡过程中,2种杂化涂层的表面形成了不同的特殊纳米结构表面形貌,这应是少量Cu_2O空心球即可使杂化涂层具有好的防污效果的原因。
[Abstract]:Cu_2O hollow spheres were prepared by soft template method and self template method respectively. The effects of reaction conditions on the morphology and properties of Cu_2O hollow spheres were investigated. The antifouling properties of the coatings prepared by using them as antifouling agents were studied. The bacteriostatic properties of Cu_2O hollow spheres were characterized and discussed by means of X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM) and bacteriostasis test. The results showed that Cu_2O hollow spheres with smooth surface and high crystallinity were obtained by soft template method, and open hollow microspheres composed of nanoparticles were prepared by self-template method. In the bacteriostatic test, when the concentration of two kinds of hollow sphere turbidity liquid is 50 渭 g / mL, the bacteriostatic effect can reach more than 95%, and the bacteriostatic effect is good. Two kinds of hybrid antifouling coatings were obtained by mixing two kinds of Cu_2O hollow spheres as antifouling agent with fluorinated block copolymer resin SBF modified resin. In the anti-algal adhesion test, there was no algal adhesion on the surface, which had good anti-fouling performance. The surface morphology of the two hybrid coatings was different during soaking, which should be the reason why a small amount of Cu_2O hollow spheres could make the hybrid coatings have good antifouling effect.
