Surface Modification of PVDF Copolymer Nanofiber by Chitosan/Ag(NP)/Nanosilica Composite

Abstract

PVDF copolymer nanofiber showed good chemical, mechanical and high hydrophobicity properties. PVDF copolymer nanofiber can be modified and functionalized by introducing hydrophilic and antibacterial materials such as chitosan composite. In this work, PVDF copolymer nanofiber with an average diameter 427.00 nm was modified by dip-coating process by using mixture of chitosan/Ag(NP)/nanosilica. Chitosan/Ag(NP)/nanosilica/PVDF copolymer nanofiber composite was successfully synthesized after analysis and confirmed by using ATR-FTIR spectroscopy, scanning electron microscopy (SEM), water contact angle and water spreading time analysis.
