“…89 An iCVD coating grafted with polysulfide surface chains also demonstrated an antibiofilm property, which was attributed to the dynamic nature of the polysulfide chains, undergoing reversible S−S bond exchange at room temperature (the cleavage/dissociation energy of which was 2/3 that of a C−C bond). 90 The grafting was enabled by a UV-activated thiol− ene reaction between the vinyl groups formed by PV4D4 and sulfur vapor. Antibiofilm performance, calculated using fouling area observed in microscopic images, demonstrated that after 24 h of incubation with E. coli the polysulfide-grafted surfaces reduced the biofilm by 41.1%, 90.3%, and 94.9% compared to polyethylene glycol (PEG), PDMS, and tissue culture polystyrene (TCPS), respectively.…”

Biofouling is a major issue across various industries ranging from healthcare to the production of food and water and transportation. Biofouling is often induced or mediated by environmental microbes, such as bacteria. Therefore, developing antibacterial coatings has been an essential focus of recent research on functional polymer thin films. To achieve high film quality, vapor-phase techniques represent promising alternatives to traditional solution-based methods, especially for the design and synthesis of antibacterial polymer coatings, as they enable highly uniform, chemically precise, and substrate-independent coatings. This Perspective examines the potential of vapor-phase polymerization techniques to create novel antibacterial polymer coatings. Current advancements in the design of antifouling, bactericidal, antibiofilm, and multifunctional coatings via vapor-phase techniques are organized based on their action mechanisms and design principles. The opportunities and challenges associated with implementing vapor-phase polymerization for developing antibacterial coatings are highlighted.

The initiated Chemical Vapor Deposition (iCVD) technique is an all‐dry method for designing organic and hybrid polymers. Unlike methods utilizing liquids or line‐of‐sight arrival, iCVD provides conformal surface modification over intricate geometries. Uniform, high‐purity, and pinhole‐free iCVD films can be grown with thicknesses ranging from > 15 μm to < 5 nm. The mild conditions permit damage‐free growth directly on to flexible substrates, 2D materials, and liquids. Novel iCVD polymer morphologies include nanostructured surfaces, nanoporosity, and shaped particles. The well‐established fundamentals of iCVD facilitate the systematic design and optimization of polymers and copolymers. The functional groups provide fine tuning of surface energy, surface charge, and responsive behavior. Further reactions of the functional groups in the polymers can yield either surface modification, compositional gradients through the layer thickness, or complete chemical conversion of the bulk film. The iCVD polymers have been integrated into multilayer device structures as desired for applications in sensing, electronics, optics, electrochemical energy storage, and biotechnology. For these devices, hybrids offer higher values of refractive index and dielectric constant. Multivinyl monomers typically produce ultrasmooth and pinhole‐free and mechanically deformable layers and robust interfaces which are especially promising for electronic skins and wearable optoelectronics.This article is protected by copyright.
