Synthesis and Characterization of Liquefied Corn Barn-Based Epoxy Resins

Article Preview

The liquefied corn barn-based epoxy resin (LCBER) was synthesised through the glycidyl etherification reaction from liquefied corn barn (LCB) had having groups of bound phenol and epichlorohydrine under alkali conditions. The average molecular weights of LCBER in various reaction conditions were examined. The extreme high molecular weight portion of LCBER-30 was obtained using LCB at 30 min as raw materials. The epoxy functionality of LCBER was controlled by the amount of bound phenol in LCB. LCBER was cured with polyamide-650 (PA-650) and the thermal and mechanical properties were evaluated. Comparing to the petroleum-based bisphenol-A type epoxy resin (DGEBA), LCBER presented higher adhesive shear strength and good thermal stability. These suggested that LCBER would be more suitable to glue biomass materials.
