conductivity of thermosetting polymers depends on the crosslink level which is very sensitive to the curing conditions [ 32 – 34 ] as well as properties of thermoplastic-thermoset blends are highly dependent on the morphology of samples [ 35 ]. Therefore

Polyfurfuryl alcohol (PFA) is a thermoset biopolymer derived from sugar cane bagasse. PFA has inherently very high thermal stability
residual stress analysis [ 4 ]. Electrically conductive adhesives consist of a polymer binder that provides mechanical strength and conductive fillers, which offer electrical conduction. Polymers are commonly classified as either thermosets (such as epoxies
thermogravimetric method [ 15 – 18 ]. Lopez et al. [ 19 ] studied the effect of thermoplastic on cure reaction and thermal stability of epoxy-amine thermoset and thermoplastic-based polymer blends, and reported that modifier did not affect the thermal and thermo
In general, the cure of thermosets such as unsaturated polyester and epoxy resins, proceeds by transformation from liquid to rubber (gel) to glass to form a rigid cross-linked structure [ 1 , 2 ]. The cure

Preparation of DGEBA–PTAC–PMDA thermoset system
Initially, DGEBA was thoroughly mixed with PTAC. Then, PMDA was gradually added to the blend with
