Inventive techniques for forming unique compositions of matter are disclosed, as well as various advantageous physical characteristics, and associated properties of the resultant materials. In particular, particles comprising polymer matrices are characterized by having carbon disposed within the polymer matrix structure thereof. The carbon is primarily, or entirely, present at interstitial sites of the polymer matrix, and may be present in amounts ranging from about 15 wt % to about 90 wt %. The carbon, moreover, forms covalent bonds with both atoms of the polymer matrix and other carbon atoms present in, but not part of, the matrix. This facilitates substantially homogeneous dispersal of the carbon throughout the resultant material, conveying unique and advantageous properties such as strength-to-weight ratio, density, mechanical toughness, sheer strength, flex strength, hardness, anti-corrosiveness, electrical and/or thermal conductivity, etc. as described herein. In some approaches, the resultant materials may be powderized or pelletized.
