Abstract Chlorinated rubber (CR)-based materials available for artificial surfaces have important commercial and industrial applications. However, CR-based materials are susceptible to diverse biofouling. In this study, different amounts (i.e. 0.2 wt % and 2 wt %) of multi-walled carbon nanotubes (MWCNTs) were incorporated into the CR matrix (CF0), respectively, in order to prepare the MWCNTs-modified CR composites (MCRCs, CF1 and CF2) with improved antifouling (AF) properties. The CR-based coatings were characterized using the SEM technique and then examined in the natural seawater via long-term field exposure assays. The impact of MCRCs on the colonization dynamics of pioneer eukaryotic microbes (PEM) in the natural biofilms with regard to their diversity, abundance, distribution patterns and succession process was investigated using the single-stranded conformation polymorphisms (SSCP) technique. MCRCs demonstrated differential surface structure features and enhanced AF properties compared with the unfilled CR matrix. The diversity and abundance of the PEM on the MCRC surfaces were found to be lower than that of the CR matrix, particularly reduced on the CF2 surfaces (P

多壁碳纳米管改性氯化橡胶基复合材料对先锋生物膜形成真核微生物定殖动力学的防污潜力

摘要 可用于人造表面的氯化橡胶 (CR) 基材料具有重要的商业和工业应用。然而，基于 CR 的材料容易受到各种生物污垢的影响。在这项研究中，分别将不同量（即 0.2 wt% 和 2 wt%）的多壁碳纳米管（MWCNTs）掺入到 CR 基体（CF0）中，以制备多壁碳纳米管改性的 CR 复合材料（MCRCs， CF1 和 CF2) 具有改进的防污 (AF) 性能。使用 SEM 技术对基于 CR 的涂层进行表征，然后通过长期现场暴露试验在天然海水中进行检查。MCRCs 对天然生物膜中先锋真核微生物 (PEM) 定植动态的影响，包括其多样性、丰度、使用单链构象多态性 (SSCP) 技术研究了分布模式和演替过程。与未填充的 CR 矩阵相比，MCRC 表现出不同的表面结构特征和增强的 AF 特性。发现 MCRC 表面上 PEM 的多样性和丰度低于 CR 基质的多样性和丰度，尤其是在 CF2 表面上降低（P
