Poly(ethylene terephthalate) and poly(acrylonitrile) fabrics are the most produced synthetic fabrics in the world. Their production and usage increase at medical textile. There is no functional group in their structure for enzyme immobilization. Hence, they are not inclined to react. However, functional groups could be added to their structure using graft polymerization. In this study, methacrylic acid was graft polymerized to poly(ethylene terephthalate) and poly(acylonitrile) fabrics. Characterization of modified fabrics was carried out and thrombin was immobilized to poly(methacrylic acid) graft polymerized poly(ethylene terephthalate) and poly(acylonitrile) fabrics using 1-Ethyl-3-(3-dimetylaminopropyl)-carbodiimide. Optimization studies were also performed for the immobilization of thrombin. Thrombin immobilized poly(methacrylic acid) graft polymerized poly(ethylene terephtalate) and poly(acrylonitrile) fabrics were reduced recalcification time 30 % and 25 %, respectively. It is the first time, an enzyme was immobilized to fabric and its in vitro applications were performed. Thrombin has not been immobilized to synthetic fabric, yet.
