Effect of prepared carbon nanotube as photo stabilizer of poly (vinyl chloride)


Thin films of poly vinyl chloride , which suffer from changes and photo degradation when exposed to atmospheric effects, were prepared so it needs to introduce additives that act as optical stabilizers as was done in the current research as carbon nanotubes have been used as a optical stabilizer of PVC polymer, which has reduced weight loss and changes that occur on the surface when these films are irradiated, the additives work by absorbing ultraviolet radiation to reduce polymer chain fracture, weight loss and Surface changes. The velocity constant was measured, the carbonyl and polyene modulus was calculated and the polymer surface was studied with a scanning electron microscope.
