Micro- and nano-fillers used in the rubber industry

In the rubber industry, multiscale fillers have been extensively used for improving mechanical, thermal, electrical performance, extending the desirable properties, and reducing the cost. The fillers used in rubber can be categorized as carbon fillers, inorganic fillers, and biofillers. Besides the traditionally used microscale particles, nanoscale fillers have been gaining more and more attentions, in both academia and industry. This chapter starts from the polymer rubber matrices, following an overview on micro- and nanofillers. The particle characteristic features and their impact on rubber properties are also discussed from the perspective of industrial progress as well as academia research focus.
