Rubber macromolecules

Although we made no attempt to elucidate the mechanism of friction decreases in rubbers after surface fluorination, it seems to us that apart from the substitution of H atoms to F in the polymer macromolecule, which forms a fluoropolymer on the surface, there is another phenomenon that makes a significant contribution to the friction decreases, i.e., fluorination of carbon black, which is used in rubber recipes for reinforcement. It appears that when the carbon black in the surface of the rubber is fluorinated it produces a lubricating effect, followed by blooming on the surface of the treated rubber while it is under a friction load. So, in our opinion, two effects contribute to friction decrease of carbon-filled rubbers fluorination of the rubber macromolecules and fluorination of the carbon black rubbers that do not contain carbon black show a much smaller decrease in friction after XeF2 treatment. [Pg.235]

Thermal stability of elastomer can be assessed from the weight loss as a function of temperature. TGA thermograms of pure NR and its composites have been shown in Fig. 4 [65]. Conventional carbon black (CB) dispersed in NR caimot increase the thermal stability of NR while CNT dispersed in NR increase the degradation temperature significantly mainly due to thermal barrier of the nanoparticles. Another reason for this improvement might be due to restriction on the mobilization of rubber macromolecules in presence of CNT and carry out heat homogeneously and avoid heat concentration [88]. On the other hand, Falco et al. has shown similar thermal stability of composites to that of pure SBR with the addition of MWCNT [29]. [Pg.24]
