Novolac Phenolic Resin

Propargyl substituted novolac phenolic resin diluted with unsaturated bisphenol-A ethers was used for glass fiber solvent-free impregnation for the formation of high-performance composites. The addition of 20% mass of diallyl (DAEBA) or dipropargyl (DPEBA) bisphenol-A to propargyl substituted novolac phenolic resin resulted in viscosity drop from 2000 mPa∙s to 400‒500 mPa∙s at 140 °C. This proved to be enough to achieve complete impregnation of the twisted glass fibers, as illustrated by SEM analysis. This improvement in impregnation was shown to result in increasing both flexural strength and modulus of the unidirectional glass fiber composite material approximately with a factor of two compared to the composite impregnated with resin without bisphenol-A ethers. DPEBA was shown to be more suitable for high-temperate applications since its addition does not seem to result in a decrease of the heat deflection temperature (HDT).

<p>The lithium ion technology is now beginning to enter into electric vehicles and grid storage of renewable energies (solar and wind energy). However, the current lithium ion technology has reached the limitations of their charge-storage capacity and energy density. Therefore, alternative cathode and anode materials that offer higher capacities need to be developed. Lithium- sulfur battery with sulfur based cathode undergoes conversion reactions while accommodating more ions and electrons as promising options to overcome the charge-storage limitations of lithium ion battery. Cost, cycle life, safety, energy, power, and environmental impact should be considered for commercializing modified lithium-sulfur batteries. In this study highly conductive and lightweight cathode materials consist of poly 1,5-diaminoanthraquinone (PDAAQ) and magnesium oxide (MgO) have been considered to increase cycle life and performance of lithium-sulfur batteries. Modified one and double side coated glass fiber separator also was investigated to improve confinement of active materials on the pores and prevented dissolution of undesired materials in the electrolyte. The cells with MgO/PDAAQ/S cathode and uncoated glass fiber separator showed initial discharge capacity of 1000 mAh g<sup>-1</sup> at 2C. The discharge capacity decreased at ~ 900 mAh g<sup>-1</sup> for 5C. MgO/PDAAQ/S cathode and double side coated glass fiber separator showed the higher capacities of ~1250 and 1170 at 2C and 5C respectively. </p>
