使用DMA和甲基丙烯酸2-羟基-3-腰果酰基丙酯（HCPM）作为单体，通过自由基聚合制备一系列含有贻贝启发的亲水性多巴胺和植物基疏水性腰果酚部分的共聚物[PCD#s，其中#是多巴胺甲基丙烯酰胺（DMA）在聚合物中的重量百分比]。PCD#s被用作涂层材料，以防止由生物污垢和油污垢的粘附引起的膜通量下降。涂覆有PCD#s的聚砜（PSf）超滤膜显示出比裸PSf膜更高的抗生物污染性，并且膜的杀菌性能随着PCD#s中HCPM单元含量的增加而增加。偶然地，涂覆有或多或少的两亲性PCD 54和PCD 74的PSf膜，具有最佳量的亲水DMA和疏水HCPM部分，显示出比更亲水的PCD 91涂覆的膜、更疏水的PCD 0涂覆的膜和裸PSf膜显著更高的耐油污性。因此，可以由含有贻贝启发的多巴胺和植物基腰果酚基团的单体制备具有生物污垢和油污垢抗性和杀菌性能的多功能涂层材料。
A series of copolymers [PCD#s, where # is the weight percentage of dopamine methacrylamide (DMA) in polymers] containing mussel-inspired hydrophilic dopamine and plant-based hydrophobic cardanol moieties was prepared via radical polymerization using DMA and 2-hydroxy-3-cardanylpropyl methacrylate (HCPM) as the monomers. PCD#s were used as coating materials to prevent flux decline of the membranes caused by the adhesion of biofoulants and oil-foulants. Polysulfone (PSf) ultrafiltration membranes coated with PCD#s showed higher biofouling resistance than the bare PSf membrane, and the bactericidal properties of the membranes increased upon increasing the content of HCPM units in the PCD#s. Serendipitously, the PSf membranes coated with the more or less amphiphilic PCD54 and PCD74, having the optimum amount of both hydrophilic DMA and hydrophobic HCPM moieties, showed noticeably higher oil-fouling resistance than the more hydrophilic PCD91-coated membrane, the more hydrophobic PCD0-coated membrane, and the bare PSf membrane. Therefore, multifunctional coating materials having biofouling- and oil-fouling-resistant and bactericidal properties could be prepared from the monomers containing mussel-inspired dopamine and plant-based cardanol groups.
