Laser stabilization of polyacrylonitrile fibers

Key Points

• Laser stabilization enhances the thermal treatment of polyacrylonitrile fibers, improving their molecular structure and mechanical properties.
• Notable increases in tensile strength and thermal stability were observed, with reductions in elongation at break by up to 20%.
• The study involves an assessment of fiber properties across various laser settings, providing insights into optimal conditions for stabilization.
• The findings underscore potential industrial applications for stronger and more durable polyacrylonitrile fibers, inviting further exploration in commercial contexts.
