| 目的 研究海洋环境下高压脉冲电场对微生物污损的抑制效果和机理。 方法 采用刷涂法制备碳纤维/ 环氧防腐涂料复合涂层,研究碳纤维长度和含量对复合涂层的介电性能和表面能的影响以及碳纤维复合涂层在高压脉冲电场作用下的杀菌性能。 结果 高频电场下,碳纤维长度和含量是影响复合涂层介电性能的主要因素,随着电场强度、频率在设定范围内增加,涂层的杀菌率显著增大;而随占空比的增大,涂层的杀菌率呈先增后减最后趋于平缓的趋势,占空比为 0. 5 时涂层的杀菌率最高达99. 8% 。 结论 掺杂 0. 1% (质量分数)5 mm 碳纤维的复合涂层介电性能优良。 高压脉冲电场对细菌具有良好杀灭效果, 涂层的杀菌率最高可达 99. 97% 。 |

| Objective To explore the inhibition effects and mechanism of high-voltage pulsed electric field (HPEF) in marine environment on microbial fouling. Methods Carbon fiber / epoxy composite anti-corrosion coating was prepared by brushing method, and the effects of the carbon fiber length and content on the dielectric properties and surface energy of the composite coating as well as the bactericidal performance of the carbon fiber composite coating in high-voltage pulsed electric field. Results The results showed that the carbon fiber length and content were the main factors affecting the dielectric properties of the composite coating under high frequency. With the increase of electric field intensity and frequency within the set range, the sterilization rate of the coating obviously increased, while with the increase of duty cycle, the sterilization rate of the coating first increased and then decreased and finally tended to be stable. When the duty cycle was 0. 5, the maximum sterilization rate of 99. 8% was reached. Conclusion The composite coating with a doping content of 0. 1% 5 mm carbon fiber had excellent dielectric properties. High-voltage pulsed electric field had a good killing effect on bacteria and the sterilization rate of the coating could reach 99. 97% . |
