A surface-modified polymer is described, comprising a polymeric material and a self-assembling monolayer covalently bound thereto. The monolayer comprises monoethylene glycolated-OH (MEG-OH); 2-(3-trichlorosilyl-propyloxy)-ethyl-trifluoroacetate (7-OEG or MEG-TFA); 2,2,2-trifluoroethyl-13-trichlorosilyl-tridecanoate (TTTA); OEGylated TTTA (OEG-TTTA); S-(2-(2-(2-(3-trichlorosilyl-propyloxy)-ethoxy)-ethoxy)-ethyl)-benzenethiosulfonate (OEG-TUBTS); or a combination thereof. Methods are described for forming a surface-modified polymer by surface activation, such as with plasma. By utilizing the surface-modified polymer to make medical equipment or devices for contacting biological fluids, a reduction in surface fouling and thrombus formation can result. Advantageously, polymeric equipment or components so modified may have a reduction in unwanted chemical interactions leading to fouling or clotting. Short trichlorosilane surface modifiers allow films to be deposited onto poly(ethylene terephthalate), polycarbonate, polypropylene, polyvinyl chloride, polyurethane, and other polymers activated using plasma.
本文描述了一种表面改性聚合物,包括聚合材料和共价结合的自组装单分子层。该单分子层包括单乙二醇醚化-OH(MEG-OH); 2-(3-三氯硅基-丙氧基)-乙基三氟乙酸酯(7-OEG或MEG-TFA); 2,2,2-三氟乙基-13-三氯硅基-十三酸酯(TTTA); OEG化TTTA(OEG-TTTA); S-(2-(2-(2-(3-三氯硅基-丙氧基)-乙氧基)-乙氧基)-乙基)-苯基硫酸酯(OEG-TUBTS); 或其组合物。本文描述了通过表面活化(如等离子体)形成表面改性聚合物的方法。通过利用表面改性聚合物制造医疗设备或接触生物流体的器件,可以减少表面污染和血栓形成。优点是,这样改性的聚合物设备或组件可能会减少导致污垢或凝血的不必要化学相互作用。短三氯硅烷表面改性剂可使薄膜沉积在聚对苯二甲酸乙二醇酯,聚碳酸酯,聚丙烯,聚氯乙烯,聚氨酯和其他使用等离子体激活的聚合物上。
