Abstract

In the medical industry, minimizing biofouling is of utmost importance as it helps to reduce bacterial adhesion and prevent cross-infection. In this study, cyclized/knotted polydivinylbenzene (PDVB), a polymer with distinctive structural features, is proposed for the first time to be utilized in the preparation of antibacterial coatings. Firstly, cyclized/knotted polydivinylbenzene (PDVB) is synthesized via deactivation-enhanced atom transfer radical polymerization (DE-ATRP). Subsequently, it is processed into coatings by employing the “grafting to” method. The obtained PDVB coatings display remarkable antibacterial activity on both glass and titanium alloy substrates owing to their unique cyclized/knotted structure, effectively inhibiting the proliferation of common pathogenic bacteria. Additionally, the coatings also exhibit excellent hydrophobicity, strong adhesion, and superior thermal stability. These research findings suggest that cyclized/knotted PDVB coatings possess outstanding physicochemical properties and demonstrate powerful antibacterial performance. It is anticipated to open up new avenues for antibacterial materials.

环化/结聚二乙烯苯（PDVB）抗菌涂料

在医疗行业，减少生物污染是至关重要的，因为它有助于减少细菌粘附和防止交叉感染。本研究首次提出将环化/结聚二乙烯基苯（PDVB）这种具有独特结构特征的聚合物用于抗菌涂料的制备。首先，通过失活增强原子转移自由基聚合（DE-ATRP）合成环化/结聚二乙烯基苯（PDVB）。随后，采用“接枝”方法将其加工成涂层。所获得的PDVB涂层由于其独特的环状/结结结构，在玻璃和钛合金基底上均表现出显著的抗菌活性，有效抑制了常见致病菌的增殖。此外，涂层还表现出优异的疏水性，强附着力和优异的热稳定性。这些研究结果表明，环化/打结PDVB涂层具有优异的物理化学性能和强大的抗菌性能。预计将为抗菌材料开辟新的途径。
