Beyond the need to find a non-toxic alternative to DiGlycidyl Ether of Bisphenol-A (DGEBA), the serious subject of non-epichlorohydrin epoxy resins production remains a crucial challenge that must be solved for the next epoxy resin generations.

Mdf Cements

Macro-defect-free (MDF) cements are cement-polymer composites and were developed by Birchall et al. three decades ago. The composites are produced by mixing small amounts of polymer and water with cement. However, they have a different production method than that of cement pastes, which was inspired by rubber production. Mixtures of cement, polymer and water are processed by using a two-roll mill. The composites are known with their high flexural strengths. Unfortunately, there are not any known commercial products using MDF cements because of their poor durability under moisture. In this study, MDF cements were prepared by using poly(vinyl alcohol--vinyl acetate) PVA, calcium aluminate cements and two different types of epoxy resins. Epoxy resins were a diglycidyl ether of bisphenol A and a mixture of a diglycidyl ethers of bisphenol A and F. Durability performance was compared with respect to biaxial flexural strengths, contact angle and atomic force microscopy (AFM) for the specimens stored in water.

Polyhedral Oligomeric Silsesquioxanes

In this paper, a type of nanoporous polyhedral oligomeric silisesquioxanes (POSS) containing eight functional groups have been synthesized and mixed with diglycidyl ether of bisphenol A (DGEBA) to form epoxy resin networks with nanostructures. The cured octa(aminophenyl) silsesquioxane (1c-POSS) and DGEBA system inherently possesses higher thermal stability and higher char yield than the control epoxy resins. Furthermore, the dielectric constant of the 1c-POSS/DGEBA material (4.36) is substantially lower than that of the neat epoxy resins (4.64) as a consequence the presence of nanoporous POSS cubes in the epoxy matrix.
