Evaluation of surface properties of epoxy–nanodiamonds composites
Source abstract
Abstract
Abstract Epoxy–matrix reinforced with nanodiamond (ND) particles, with ND content up to 5 wt%, were synthesized. Characterization of NDs by field emission scanning electron microscopy (FE-SEM) and Raman spectroscopy was conducted, while composites were characterized through contact angle, nanoindentation, nanoscratch and scanning probe microscopy. The assessed properties evaluated were hardness, elastic modulus, contact angle, deformation mechanisms, creep deformation, coefficient of friction and adhesion, namely. Results showed that even small additions of ND lead to significant enhancement in the hardness and elastic modulus of epoxy matrix, while properties of composites present a switch in behavior after passing a concentration threshold; this threshold was identified and discussed.
