实验结果显示球磨8小时后原碳纳米管的封闭端头被打开，并在纳米管壁上产生了扭曲变形的石墨层。

The results show that a part of closed ends of the tubes were broken and graphite layer of some nanotubes were tortured while ground for 8h.

研究表明，与传统炭黑增强样品相比，碳纳米管在橡胶中的混入速度快，温升幅度小，混炼胶的硫化返原现象减轻。

The results showed that the nanotubes mixed rapidly into the rubber with little temperature increase during the mixing. The curing reversion of rubber composites was also reduced.
