Abstract
The present paper addresses the usefulness of a sorption gravimetric technique to assess of the compatibility and reinforcing effect of nanofiller against hazardous liquid media. The reinforcing capability of organoclay (Cloisite 30B) in chlorosulfonated polyethylene (CSM) was characterized by means of transport properties such as diffusion, sorption and permeation coefficients, activation energy, enthalpy, and entropy. The CSM/organoclay nanocomposites were prepared by melt mixing method. The transport of toluene through CSM vulcanizates were studied with special reference to the effect of organoclay concentration (0–9 parts per hundred parts of rubber) and temperature (25–55°C). The microstructure of the nanocomposites was confirmed by studying of dispersion of organoclay in CSM via transmission and scanning electron microscopy and X‐ray diffraction. The results showed that the swelling properties of nano‐filled CSMs mainly depend on the presence of organoclay and not its concentration and also the formed microstructure. A good relationship was found between the microstructure and swelling properties of CSM nanocomposites. J. VINYL ADDIT. TECHNOL., 23:E40–E50, 2017. © 2016 Society of Plastics Engineers
