“…This need is particularly pressing in the automotive, wind energy, aerospace and microelectronics industries where petroleum derived epoxy resins are abundantly used due to their superior thermal and mechanical properties, dimensional stability, chemical resistance, electrical insulation, and good wettability with substrates for composite fillers and structural adhesives. [1] These industries have driven global epoxy production to 2 million tons in 2010 and over 20 billion dollars annually. [2] The diglycidal ether of bisphenol A (DGEBA) makes up the vast majority (~90%) of all epoxies produced.…”

Biobased epoxy nano-composites composed of untreated multi-wall-carbon-nanotubes (MWCNT) and diphenolic acid-derived biobased epoxy: diglycidyl ether of diphenolate n-butyl ester (DGEDP-Bu), were fabricated. Electrical, rheological, and mechanical percolation thresholds were compared between biobased and commercial bisphenol A (DGEBA) epoxy composites. For both epoxies, nanocomposites loaded with 0.05 -0.2 wt % MWCNT's exhibited electrical and rheological percolation at 0.05 wt % and 0.2 wt % respectively. DMA and tensile results revealed that DGEDP-Bu composites exhibited equivalent or superior properties to DGEBA composites. With 0.2 wt % MWCNT's, DGEDP-Bu nanocomposites exhibited 68 % higher electrical conductivity and a three-fold higher rheological yield stress than those made from DGEBA. Rheological characterization corroborated that continuous MWCNT networks are formed within epoxies between 0.1 and 0.2 wt % MWCNT's. Moreover, upon MWCNT loading, DGEDP-Bu demonstrates equal mechanical performance and better electrical conductivity than DGEBA.
