    摘要： Disclosed is a rubber composition for tire treads and a tire manufactured using the same. More particular, the rubber composition for tire treads includes 50 to 200 parts by weight of a wet masterbatch prepared by reacting a styrene-butadiene latex, a carbon black and a liquid styrene-butadiene copolymer at 50 to 95° C. for three to nine hours according to a batchwise method, 60 to 70 parts by weight of a raw rubber, and 50 to 200 parts by weight of a carbon black. Accordingly, the rubber composition for tire treads has enhanced grip and anti-wear performances under a condition of heavy load, high slip and high speed, and thus, may be usefully used in manufacturing a ultra-high performance tire.

    摘要： Structured films containing multi-walled carbon nanotubes (“MWCNTs”) have enhanced mechanical performance in terms of strength, fracture resistance, and creep recovery of polyimide (“PI”) films. Preferably, the loadings of MWCNTs can be in the range of 0.1 wt % to 0.5 wt %. The strength of the new PI films dried at 60° C. increased by 55% and 72% for 0.1 wt % MWCNT and 0.5 wt % MWCNT loadings, respectively, while the fracture resistance increased by 23% for the 0.1 wt % MWCNTs and then decreases at a loading of 0.5 wt % MWCNTs. The films can be advantageously be created by managing a corresponding shift in the annealing temperature at which the maximum strength occurs as the MWCNT loadings increase.
