Abstract
Expanded graphite (EG) and hydrogenated natural rubber (HNR) latexes with the hydrogenation conversion of 60 and 95 mol% (HNR60 and HNR95, respectively) were prepared according to our proposed procedure, and they were blended in the latex stage. The characterization of EG was determined through BET surface area determination, XRD, and SEM. The investigation of HNR/EG blends was carried out through the tensile property measurement, weather resistance determination, electromagnetic shielding efficiency measurement, and TEM observations. The SEM images and the angles of X‐ray diffraction of EG showed the significant expansion of the graphite and graphitic carbon structure with the interlayer spacing (d) of 3.357 Å. The EG was porous with 91.2146 m2/g of BET‐specific surface by N2 adsorption/desorption isotherms measurements. The highest tensile property, weather resistance, and electromagnetic shielding efficiency of HNR60 were achieved when the amount of dispersed EG was 10%. In contrast, those of HNR95 were achieved when the amount of dispersed EG was 12%. EG was found to be well dispersed in HNR95 than HNR60 as being verified through TEM and FIB‐SEM observations.
