             abstract = "Polymer composites containing modified graphite structures as 
                         fillers have been successfully processed exhibiting attractive 
                         features for different applications. Carbon foams derived from 
                         polymer precursor is brittle and the addition of some 
                         reinforcement to produce them is of great interest not only to 
                         improve their mechanical properties, but also to use them for 
                         multifunctional purposes. Considering the advantages provided by 
                         different modified graphite structures added to polymer 
                         composites, including low price, ease of dispersion, good thermal 
                         stability, electrical conductivity, and mechanical properties, 
                         expanded graphite (EG) was chosen as filler for the carbon foams 
                         processing to produce reticulated vitreous carbon (RVC) 
                         composites. Poly(furfuryl alcohol) was used as the carbon matrix 
                         precursor and different amounts of EG were dispersed in the resin 
                         to impregnate the polyurethane foam template. The RVC_EG 
                         composites were analyzed by scanning electron microscopy, Raman 
                         spectroscopy, X-ray diffraction, compression test, and cyclic 
                         voltammetry. EG presence on RVC_EG composites showed synergic 
                         effects contributing to their crystallinity, compressive strength, 
                         and charge transfer reactions improvement as well as their 
                         specific electrochemical surface area increase. Therefore, the 
                         effectiveness of the resulting carbon composite was mainly 
                         attributed to the good interaction between EG and carbon matrix.",
