通过表面介导性聚合进行的表面改性需要控制接枝聚合物膜的厚度以实现所需的性能变化。这里，使用微阵列格式来快速评估关于所获得的膜厚度和聚合行为的一系列反应条件和配方。对不同浓度聚乙二醇二丙烯酸酯(PEGDA)、N-甲基二乙醇胺(MDEA)和1-乙烯-2-吡咯烷酮(VP)的曙红偶联物引发的单体配方进行了评价。还考察了以MDEA或抗坏血酸为共引发剂的丙烯酰胺。最佳配方是40wt%丙烯酰胺和MDEA，与相应的PEGDA配方相比，它可以产生4到8倍厚的薄膜(最大聚合物厚度从180 nm增加到1420 nm)，并从较低的曙红表面密度(2.8比14曙红/微米2)产生5倍的可见膜。使用微阵列形式来评估多个引发剂表面密度，使得能够在所需的引发剂表面密度范围内容易地识别产生所需聚合物性能和聚合行为的单体配方。
Surface modification by surface-mediated polymerization necessitates control of the grafted polymer film thicknesses to achieve the desired property changes. Here, a microarray format is used to assess a range of reaction conditions and formulations rapidly in regards to the film thicknesses achieved and the polymerization behavior. Monomer formulations initiated by eosin conjugates with varying concentrations of poly(ethylene glycol) diacrylate (PEGDA), N-methyldiethanolamine (MDEA), and 1-vinyl-2-pyrrolidone (VP) were evaluated. Acrylamide with MDEA or ascorbic acid as a coinitiator was also investigated. The best formulation was found to be 40 wt% acrylamide with MDEA which yielded four to eight fold thicker films (maximum polymer thickness increased from 180 nm to 1420 nm) and generated visible films from 5-fold lower eosin surface densities (2.8 vs. 14 eosins/µm2) compared to a corresponding PEGDA formulation. Using a microarray format to assess multiple initiator surface densities enabled facile identification of a monomer formulation that yields the desired polymer properties and polymerization behavior across the requisite range of initiator surface densities.
