Unlock Enhanced Polymer Properties With Spray And Stretch Processing: A Guide To Molecular Orientation And Crystallization

Spray and stretch processing is a technique that utilizes the principles of polymer relaxation and viscoelasticity to induce molecular orientation and crystallization in polymers. It involves spraying a polymer solution onto a substrate, where the solvent evaporates, causing the polymer chains to stretch and align. This orientation results in enhanced mechanical properties, including improved tensile strength, modulus, and toughness. The process involves a series of steps, including understanding the fundamentals of polymer relaxation and viscoelasticity, the spray-induced stretch technique, and the post-processing effects such as necking, draw ratio, crystallinity, and orientation.
