Diglycidyl Ether of Bisphenol A (DGEBA) Based Epoxy Sizing Agent Induces Surface Polarity in Carbon Fibers†
Abstract: Determination of the chemical structure and composition of the sizing agent is a challenge as its concentration is low, varying in the range from ~0.5 wt.% (for polyacrylonitrile, PAN, based carbon fibers) to ~1 wt.% (for pitch-based carbon fibers). Moreover, such a piece of knowledge is vital for designing compatible polymer matrices to prepare CFRPs for diverse applications. As a result, the sizing layer that is coated on the carbon …

Tribological Assessment of Chemically Modified Jatropha Curcas Oil Developed by Addition of Graphite Nanoparticles for Biolubricant Applications
Abstract: As an alternative to petroleum-based lubricants, environmentally friendly bio-based lubricants are gaining popularity in the lubrication industry. A sustainable bio-based lubricant, Jatropha Curcas Oil (JCO) incorporates nanoparticles as additives. Nevertheless, this oil cannot be used directly as a biolubricant due to its low oxidative stability. By redesigning the oil's molecular structure through chemical modification, this restriction can be overcome. Epoxidation and oxirane ringopening were the two steps used in this …

Modified Oil Bitumen with Polymer Waste for Oil Pipeline Application from Bitu
Abstract: Protection of oil refining, oil production and gas pipeline equipment from corrosion is the most important problem today. Currently, anticorrosive materials are mainly used, resistant polymer compositions, epoxy resin, bitumen and other materials for coating metal parts of these equipment. But these anticorrosive materials do not always provide metals from corrosion at the metal-antioxidant boundary and do not provide high strength of the protective layer, so these anticorrosive materials do …
