Fabrication of Poly vinyl alcohol Sericin nanofibrous Scaffold through Electrospinning Sanaz Eslah Sanaz eslah@yahoo com Date of Submission Department of Textile Engineering Isfahan University of Technology Isfahan 8415683111 Iran Degree M Sc Language Farsi Supervisor Prof H Tavanai tavanai@cc iut ac ir Prof M Morshed morshed@cc iut ac ir Abstract Poly vinyl alcohol is a hydrophilic biocompatible and biodegradable polymer which has found application in biodrugs and tissue engineering Up to present time polyvinyl alcohol has been electrospun from aqueous solution Sericin accompanying Silk is a waste which is produced in scouring silk and has interesting properties which has attracted the attention of researchers Sericin is hydrophilic biodegradable biocompatible cheap and enjoys anti cancer properties Mixture of poly vinyl alcohol and sericin in the form of 2D membrane or 3D hydro gels has been employed in healing skin damages and has proved to be successful Adding sericin to polyvinyl alcohol has improved the adhesion proliferation and growth of cells on poly vinyl alcohol tissue engineering scaffolds In this research polyvinyl alcohol 100 was electro spun from an organic solvent solution of PVA in DMSO dimethyl sulfoxide Up to now only aqueous solution of PVA has been electrospun More over the mixture of PVA Sericin was also electro spun in a common organic solvent namely DMSO The electrospinning solution contained ratio of 0 100 10 90 15 85 20 80 and 25 75 sericin w w PVA w w Addition of urea to the solution made electrospinning of PVA Sericin easier The electro spun PVA Sericin nano fibers had diameter in the range of 179 285nm The effect of electrospinning parameters like voltage feed rate and nozzle collector distance was investigated on the diameter of electrospun nano fibers XRD and DSC investigations showed that no reaction occurs between PVA and sericin as a result of mixing them Keywords poly vinyl alcohol sericin electrosinning nano fibers tissue engineering
