Abstract

Multiwalled carbon nanotube (MWCNT) reinforced chlorobutyl elastomer nanocomposites were prepared. Bound rubber (BdR) is considered as a measure of the filler-polymer interaction in elastomer compounds. The variation of the BdR content with storage time was studied in chlorobutyl compounds filled with multiwalled carbon nanotube fillers. The BdR content increased with storage time in all compounds. The increase in BdR was higher during the initial 15 days of storage. Thereafter there was only a marginal increase. The morphology of nanocomposite samples has been also studied from scanning electron microscope (SEM) photographs.
