Uniform dispersion of the constituent nanomaterial is essential in attaining optimal results for nanocomposite fabrication. In this research, a dual-phase dispersion method is studied combining a high intensity ultrasonic liquid processor with a three roll milling technique. XD-grade carbon nanotubes (XD-CNTs) were infused into Epon 862 epo.xy and the mixture was then mechanically mixed with a mechanical stirrer before placing into a sonicator. This mi.xture was submerged continuously in a cooling bath to prevent premature polymerization. Once the sonication cycle was completed, the mixture was then placed in a three roll milling processor for six .tucce.
Major limitation for use of epoxy thermosets in engineering applications is its sudden brittle failure. In the present study dipropylene glycol dibenzoate (DPGDB) based plasticizer is used to modify diglycidyl ether of bisphenol A (DEGEBA) based epoxy resin system via simple blending technique. Bio‐based epoxidized linseed oil was also used to modify epoxy resin system and compared with DPGDB modified resin. For DPGDB modified resin storage modulus and loss modulus of the epoxy system modified with 10% plasticizer increased by 7.54% and 12.24%, respectively. The primary mechanism responsible for such behavior is improved crosslinking density. With 5% plasticizer loading, flexural strength increased by 21%. There was an improvement of 312.74% in strain at failure for 10% plasticizer loading, while preserving its mechanical strength. It was found that DPGDB based modification was better than epoxidized linseed oil modification.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
