Abstract EN
A wide number of polymers are being used for various medical applications.
In this work, microwave-assisted surface modification of metallocene polyethylene (mPE) was studied.
FTIR analysis showed no significant changes in the chemical groups after treatment.
Contact angle analysis revealed a decrease in contact angle of the treated samples insinuating increasing hydrophilicity and better biocompatibility.
Qualitative analysis of treated samples using scanning electron microscope (SEM) depicted increasing surface roughness and holes formation further corroborating the results.
Coagulation assays performed for estimating prothrombin time (PT) and activated partial thromboplastin time (APTT) showed an increase in the clotting time which further confirmed the improved blood compatibility of the microwave-treated surfaces.
Further, the extent of hemolysis in the treated sample was lower than the untreated one.
Hence, microwave-assisted surface modification of mPE resulted in enhanced blood compatibility.
Improved blood compatibility of mPE may be exploited for fabrication of artificial vascular prostheses, implants, and various blood contacting devices.
