A Study on Fabrication Technique, Properties, and Applications of PAN Nanofibers
Summary of Doctoral Thesis
Jaymin Vrajlal Sanchaniya, Riga Technical University, Latvia
The domain of nanotechnology, particularly the exploration and utilization of nanofibers, offers unrivalled opportunities for innovation across various fields. This Doctoral Thesis delves into the sophisticated world of polyacrylonitrile (PAN) nanofibers, focusing on their fabrication, mechanical and thermal characteristics, and potential applications. Through an exhaustive literature review and rigorous experimental investigations, this work aims to bridge significant gaps in the existing knowledge of nanofiber technology. The research meticulously explores the experimental fabrication of PAN nanofiber mats using various electrospinning methods and formulates a validated finite element model to accurately predict their mechanical behaviour. The impact of structural orientation, annealing, and PVA doping on the nanofiber mats’ mechanical and thermal properties is extensively investigated. The novel dip-coating method with PVA doping significantly enhances the elastic modulus and ultimate tensile strength of the nanofiber mats. Furthermore, the direct electrospinning of nanofibers onto textiles demonstrates the potential of creating non-crimping textile composites integrated with PAN nanofibers for diverse applications.
