Effect of Radiofrequency Plasma Assisted Grafting of Polypropylene on the Properties of Muga Silk Yarn

Development of advanced antimicrobial and sterilized plasma polypropylene grafted muga (antheraea assama) silk as suture biomaterial

“…There has always been a great research interest to modify the surface properties of natural biomaterials with an aim to enhance their performance for specific application. In this regard, several studies reveal that surface modification of AASF may also increase its efficiency as novel biomaterial by improving its physico‐chemical and mechanical properties, biocompatibility and bio‐functionality . Surface modification of AASF can be achieved through various available techniques such as wet chemical, radiation (ultraviolet radiation and laser), and plasma graft polymerization .…”

Surface modification of AASF can be achieved through various available techniques such as wet chemical, radiation (ultraviolet radiation and laser), and plasma graft polymerization . Among these techniques, plasma graft polymerization is considered as the most convenient and preferred one as it is environmentally friendly and non‐hazardous, consumes less chemical, energy and time and processes materials at low temperature (<100°C) .…”

Besides, unlike wet chemical and radiation grafting, plasma grafting has the advantage of modifying surface properties of materials up to few nanometer depth without degrading their intrinsic bulk properties . This opens up possibilities to develop novel biomaterials that must possess bulk properties to meet other requirements, especially mechanical properties to permit their function in the bio‐environment, but also the best surface properties.…”
