Abstract
Exposure of Ultraviolet (UV) light cause negative health effects to human and also reason for the photodegradation of organic compounds. In this framework study and development polymer based of UV shielding materials with visible transparency gains lot of attention. In the present research work, Poly(VinylAlcohol) (PVA) polymer based UV-shielding material fabricated by using 4-Hydroxy Benzophenone (Ph2CO) as UV-absorber. 4-Hydroxy Benzophenone (Ph2CO) is an organic compound were synthesized by Fries rearrangement. Subsequently, (PVA)/Ph2CO composite films were synthesized by an employing simple solvent casting technique. Optical studies revealed that PVA/Ph2CO films shows good UV-shielding competency and practically shield the whole UV region (200–400 nm). This outstanding UV shielding properties of the fabricated films arises mainly because of interaction of Ph2CO with polymer matrix. Additionally, optical constants are also calculated by using optical absorbance data. Surface properties of the fabricated films is evaluated using Scanning Electron Microscopy (SEM) and structural properties by X-ray Diffractometer (XRD). Elemental analysis is carried out using EDAX. The obtain results shows that the developed composite film have improved optical properties like short band gap with UV shielding possessions. Hence, the prepared composite films can be employed as a novel next generation transparent UV shielding materials.
