从香草醛衍生的生物基单体开发了新的抗菌PET表面。采用一步法合成了N-（4-羟基-3-甲氧基苄基）丙烯酰胺单体。采用两步法对PET进行改性：首先用N，N-二乙基乙二胺对PET进行氨解接枝，然后用“接枝自”技术对生物基丙烯酰胺单体进行光聚合。通过XPS、紫外-可见光谱和水接触角测试对PET表面改性进行了表征。最后，进行抗粘附生物测试，以评估改性表面对革兰氏阳性菌（红球菌和金黄色葡萄球菌）和革兰氏阴性菌（大肠杆菌和铜绿假单胞菌）的潜在抗菌性能。
New antibacterial PET surfaces were developed from vanillin-derived biobased monomer. An easy one-step and high yielding synthesis ofN-(4-hydroxy-3-methoxybenzyl)-acrylamide monomer was successfully achieved. PET was modified by a two-step procedure: Type II photoinitiator was first grafted through a PET aminolysis withN,N-diethylethylenediamine, then the photopolymerization of the biobased acrylamide monomer was performed according to a “grafting from” technique. PET surface modifications were characterized by XPS and UV–visible spectroscopies, as well as water contact angle measurements. Finally, antiadhesion biotests were conducted to evaluate the potential antibacterial performances of the modified surfaces against gram-positive (Rhodococcus wratislaviensisandStaphylococcus aureus) andgram-negative (Escherichia coliandPseudomonas aeruginosa)strains.
