Effect of gamma irradiation on the optical properties of UHMWPE (Ultra-high-molecular-weight-polyethylene) polymer

Thermal, Mechanical and Rheological Behaviors of Nanocomposites Based on UHMWPE/Paraffin Oil/Carbon Nanofiller Obtained by Using Different Dispersion Techniques

“…For these reasons, UHMWPE is widely utilized in technological applications in the field of medicine, biomaterials, microelectronics, engineering, chemistry and the food industry among many others [2][3][4].…”

“…Zhang et al (2011) blended UHMWPE with PO by using a HAAKE HBI System without extracted PO to increase the crystallization behaviors [13]. Instead Shilei Lio et al (2014) studied the effect of the PO mixed to the UHMWPE by magnetic stirring and they evidenced as the paraffin oil reduces the fusion defects 4 of UHMWPE induced by the working techniques; this improved its mechanical and physical properties [14].…”

Radiation-induced oxidation of ultra-high molecular weight polyethylene (UHMWPE) powder by gamma rays and electron beams: A clear dependence of dose rate

“…Because of its high chemical resistance (Raghuvanshi et al, 2012;Zhao et al, 2011), excellent biocompatibility (Ravanbakhsh et al, 2010) and mechanical properties (Torrisi et al, 2007), ultrahigh molecular weight polyethylene (UHMWPE) is useful in many fields, such as medical devices, engineering (Raghuvanshi et al, 2012) and defense supplies (Stephens et al, 2007). One of the most outstanding properties of UHMWPE is its desirable anti-wear performance.…”

Gamma Radiation Induced Modifications on Physicochemical Properties of Makrofol (KG and N) Polycarbonate

“…The spectra shows a shift in the optical absorption edge of irradiated samples toward red end of the spectrum, which increases with the increase in gamma dose, indicating a growing concentration of conjugated system of bonds. 6 Owing to this shift, the optical band gap energy (E g ) of the polymers decreased, which was calculated by applying Tauc's relation 14,15 for direct transitions as per the following equation:…”

“…3 Effects of gamma irradiation on different polymers have been reported in the literature. [4][5][6] In the present study, we have taken two polymers makrofol-KG and makrofol-N. Both are PCs having same chemical composition (C 16 H 14 O 3 ), but makrofol-KG (MF-KG) is colorless, monoaxially oriented, and crystallized, whereas makrofol-N is cast isotropic and is of light yellow color.…”
