Provided are methods of preparing an electrically activated shape memory polymer composite capable of thermal shape reformation using electric power to heat the composite through its matrix glass transition temperature. The methods may include providing a polymer matrix component comprising a diglycidyl ether resin and at least one curing agent, adding into the polymer matrix component at least one nano-filler component, sonication and mixing the polymer matrix component and the nano-filler component to form a mixture, curing the mixture under curing conditions, and laminating the cured mixture with at least one elastic laminated layer.
