Abstract

A novel photopolymerizable (meth)acrylate oligomer syrup modified with ferulic acid (FA) was verified as an antimicrobial coating binder against a biofilm of . A solution-free UV-LED-initiated photopolymerization process of aliphatic (meth)acrylates and styrene was performed to prepare the oligomer syrup. The influence of ferulic acid on the UV crosslinking process of the varnish coatings (kinetic studies using photo-DSC) as well as their chemical structure (FTIR) and mechanical (adhesion, hardness), optical (gloss, DOI parameter), and antibacterial properties against were investigated. The photo-DSC results revealed that FA has a positive effect on reducing the early occurrence of slowing processes and has a favorable effect on the monomer conversion increment. It turned out, unexpectedly, that the more FA in the coating, the greater its adhesion to a glass substrate and hardness. The coating containing 0.9 wt. part of FA exhibited excellent antimicrobial properties against , i.e., the bacterial number after 24 h was only 1.98 log CFU/mL. All the coatings showed relatively high hardness, gloss (>80 G.U.), and DOI parameter values (30-50 a.u.).

摘要

一种用阿魏酸（FA）改性的新型可光聚合（甲基）丙烯酸酯低聚物糖浆被证实是一种针对[具体生物膜名称未给出]生物膜的抗菌涂层粘合剂。通过无溶液的紫外发光二极管引发的脂肪族（甲基）丙烯酸酯和苯乙烯的光聚合过程来制备低聚物糖浆。研究了阿魏酸对清漆涂层紫外交联过程（使用光差示扫描量热法进行动力学研究）及其化学结构（傅里叶变换红外光谱法）、机械性能（附着力、硬度）、光学性能（光泽度、DOI参数）以及针对[具体细菌名称未给出]的抗菌性能的影响。光差示扫描量热法结果表明，阿魏酸对减少早期出现的减缓过程具有积极作用，并且对单体转化率的增加具有有利影响。出乎意料的是，涂层中阿魏酸含量越高，其对玻璃基材的附着力和硬度就越大。含有0.9重量份阿魏酸的涂层对[具体细菌名称未给出]表现出优异的抗菌性能，即24小时后的细菌数量仅为1.98 log CFU/mL。所有涂层均显示出相对较高的硬度、光泽度（>80光泽单位）和DOI参数值（30 - 50任意单位）。
