Effect of Graphite Concentration on the Tribological and Mechanical Properties of Filled SU-8 Polymer

Different concentrations of graphite powder (particle size < 20 μm) were added for the enhancement in mechanical and tribological properties of SU-8 polymer. The materials were studied as thick coatings with thickness in the range of ~ 35-40 μm on glass substrate. SU-8 and SU-8/...
