Polyethylene glycol degradation by UV irradiation
Degradation or polyethylene glycol has been studi ed by UV irradiation. A drastic change in the morphology from spherulite to rhythmic pattern has been observed under polarized light microscope when exposed to UV light. Molecular weight of PEG. Rr value and melting point have been recorded after UV exposure. On UV exposure there has also been a change in UV. IR and powder X-ray diffraction patt...
متن کاملReversible Hydrophobic to Hydrophilic Transition in Graphene via Water Splitting Induced by UV Irradiation
Although the reversible wettability transition between hydrophobic and hydrophilic graphene under ultraviolet (UV) irradiation has been observed, the mechanism for this phenomenon remains unclear. In this work, experimental and theoretical investigations demonstrate that the H2O molecules are split into hydrogen and hydroxyl radicals, which are then captured by the graphene surface through chem...
متن کاملSurface modification of starch based biomaterials by oxygen plasma or UV-irradiation.
Radiation is widely used in biomaterials science for surface modification and sterilization. Herein, we describe the use of plasma and UV-irradiation to improve the biocompatibility of different starch-based blends in terms of cell adhesion and proliferation. Physical and chemical changes, introduced by the used methods, were evaluated by complementary techniques for surface analysis such as sc...
متن کاملUV-irradiation induced modification of PDMS films investigated by XPS and spectroscopic ellipsometry
UV-irradiation (172 nm) induced changes of PDMS surfaces were investigated with X-ray photoelectron spectroscopy (XPS) and spectroscopic ellipsometry (SE). Both methods indicate the modification of the PDMS to a silicalike surface (SiO2). These conclusions could be drawn from the elemental composition determined by XPS and the binding energy shifts in the XPS spectra of the Si 2p and O 1s level...
متن کاملPhotocatalytic Degradation of p-Cresol by Zinc Oxide under UV Irradiation
Photocatalytic degradation of p-cresol was carried out using ZnO under UV irradiation. The amount of photocatalyst, concentration of p-cresol and pH were studied as variables. The residual concentration and mineralization of p-cresol was monitored using a UV-visible spectrophotometer and total organic carbon (TOC) analyzer, respectively. The intermediates were detected by ultra high pressure li...
