Abstract
This study investigates applying TiO2 (titanium dioxide) nanoparticles to polypropylene nonwoven fabrics via electrospinning for the development of UV-protective materials. To fabricate uniform nanocomposite fibers, three types of TiO2 nanoparticles were applied: powder, colloid, and TiO2, coated polymer pellets. TiO2/polyurethane (PU) and TiO2/poly(vinyl alcohol) (PVA) nanocomposite fibers were electrospun and the morphology was examined using a field-emission scanning electron microscope and a transmission electron microscope. Layered fabric systems with electrospun TiO2 nanocomposite fiber webs were developed at various concentrations of TiO2 in a range of the web area density. The effects of TiO2, concentration and web area density on UV-protective properties were examined. When TiO2 colloid was added into a PVA polymer solution, uniform nanocomposite fiber webs in which TiO2 particles were evenly dispersed were produced. Water-soluble PVA nanofiber webs were given a heat treatment to stabilize the electrospun PVA fibrous structure against dissolution in water. TiO2/PVA nanocomposite fiber webs with 2wt% TiO2, and 3.0g/m2 web area density exhibited an ultraviolet protection factor of greater than 50, indicating excellent UV protection.
