Description
Summary:The paper reports the study of surface roughness based opto-mechanical properties of Chlorobutyl (CIIR)/Natural Rubber (NR) 70/30 polymers filled with different contents of hybrid (CB/CN) using indigenously designed THz spectrophotometer between 1 and 2.0 THz range. The carbon black (CB) and Carbon nano powders were mixed between 20 and 2.0–7.5 Phr range in the chlorobutyl and natural rubber matrix for improvising their surface quality and mechanical strength. The physical and structural changes were ascertained in terms of transmission, refractive indices and absorption coefficients. The percentage of filler also influences the morphology and surface roughness quality of the rubber due to intercalation and measured in terms of surface roughness factor ‘g’ optical impedance ‘z’ and reflection coefficients between 0.1 and 2.0 THz range. The obtained values of optical impedance lie between 220.2 and 235.6 Ω range and were correlated with the mechanical strength of the rubber samples. It provides a new modality to understand the effect of fillers on the strength of rubber samples.
