Amphiphilic surfaces are particularly effective at inhibiting the adhesion of microorganisms (bacteria, cells, microalgae, etc.) in liquid media. The aim of this study is to determine the best hydrophilic linker to promote bonding between poly(ethylene glycol) (PEG) as a hydrophilic additive and poly(dimethyl siloxane) (PDMS) as the hydrophobic matrix. Various parameters have been studied (molecular weight, linker type, and polymer end-group), as well as the efficiency of the linking, the capacity of PEG to access to the surface of the film, and overall film homogeneity. According to the results, a PDMS linker paired with a PEG moiety allows for compatibilization of the compounds during cross-linking. This compatibilization seems to provide a good bonding with the matrix and a good surface access to the hydrophilic moiety. Therefore, this structure comprising a linking function attached to the PDMS⁻PEG copolymer has high potential as a non-releasable additive for amphiphilic coating applications.
两亲性表面在抑制液体介质中微生物（细菌、细胞、微藻等）的粘附方面特别有效。本研究的目的是确定最佳的亲水性连接基，以促进作为亲水性添加剂的聚乙二醇（PEG）与作为疏水性基质的聚二甲基硅氧烷（PDMS）之间的键合。研究了各种参数（分子量、连接基类型和聚合物端基），以及连接效率、PEG接触膜表面的能力和整个膜的均匀性。根据结果，与PEG部分配对的PDMS连接基可在交联过程中使化合物相容。这种相容性似乎能与基质形成良好的键合，并使亲水性部分能很好地接触表面。因此，这种包含连接到PDMS-PEG共聚物上的连接功能的结构作为两亲性涂层应用的不可释放添加剂具有很高的潜力。
