Cationically Polymerized Epoxy and Radiation-Cured Acrylate Blend Nanocomposites Based on WS2 Nanoparticles Part B: Mechanical and Physical Properties

The radiation curing paradigm of opaque WS2 nanoparticle (NP)-based epoxy/acrylate nanocomposites was studied and found to exhibit both a reduction in viscosity an enhanced degree when incorporating NPs. objective this study investigate the mechanical, thermal, physical properties radiation-induced cured blend containing 0.3 1.0 wt.% Experimental results indicate that tensile toughness increased by 22% upon optimizing NP content compared WS2-free formulations. Tensile fractured surfaces with different contents were analyzed scanning electron microscope atomic force showed distinctive morphology depending on content, supporting test. energy required break shear adhesion specimens demonstrated increase up 60% neat resin. glass transition temperature determined dynamic mechanical analysis presented similar or higher values incorporation. Furthermore, 80% improvement impact strength NPs dispersed blend. It concluded surface chemistry dispersion level are major variables affecting macro cationically radiation-cured resins their properties. This is first demonstrate possibility for based serve as reinforcement at low concentrations enhancement curing.
