Polyvinyl alcohol (PVA) fiber is a synthetic fiber produced from polyvinyl alcohol polymer. It is characterized by high tensile strength, chemical resistance, and excellent bonding with matrices in composites. PVA fiber is widely used in reinforcement applications, biomedical scaffolds, and filtration materials due to its stability, biodegradability, and compatibility with water-soluble and hydrophilic systems.
PVA fiber exhibits limited elasticity compared to conventional elastomeric fibers. While it can tolerate some elongation before breaking, its high crystallinity and strong hydrogen bonding result in a relatively low elongation at break. This property makes it ideal for reinforcing composites rather than applications requiring high stretchability or recovery.
PVA fiber possesses high tensile strength, low elongation, chemical and thermal stability, and strong adhesion to hydrophilic matrices. It is water-soluble before crosslinking, highly crystalline, and resistant to oils and solvents. These properties make it suitable for medical sutures, reinforced concrete, composites, and filtration membranes, combining durability with environmentally friendly characteristics.
PVA nanofiber is an ultrafine fiber with diameters in the nanometer range, typically produced via electrospinning. It exhibits extremely high surface area, porosity, and flexibility while retaining the intrinsic properties of PVA, such as biocompatibility and chemical stability. PVA nanofibers are widely used in biomedical scaffolds, filtration, wound dressing, and drug delivery systems due to their nanoscale architecture.
