Abstract

Synthetic rubber is the one of the most common types of material used in Malaysia due to their ease of use. Synthetic rubber have different type properties and manufacturers and suppliers are producing different range of rubber products which are used for commercial and industrial purpose. Nanocomposite technology is a new era of rubber material, using a carbon nanotube (CNT) called nanofiller mixed with chloroprene rubber (CR) to improve mechanical properties, heat, dimensions and barriers. CNT loss during chloroprene rubber compounding. This is due to CNT is light weight, thus easily loss to surrounding. Consequently, it is difficult to control amount of CNT added during the compounding. The CNT reinforced has very high rigidity good gas barrier properties and fire resistance. CNT plays a role to enhancing mechanical properties and also reducing the impact properties of CR. This research is to investigate effect of CNT dispersion concentration on CR compounding rheology behavior and to characterize tensile strength and hardness of the CNT-reinforced CR composite after curing. CNT particles were dispersed into an intermediate medium by mixing functionalized the CNT into CR matrix. The mixing method reduced CNT loss to environment because the CNT particles are bound by attractive forces generated by interaction between the CNT particles and liquid medium. CNT’s functionalization is enable good coupling between the CNT particles and the rubber matrix. The functionalization changes the chemical and mechanical properties of CNT reinforced CR.
