The effect of nanosized carbon additives on the properties and crystallisation of polypropylene was investigated. It was shown that the introduction of carbon nanoparticles affects the crystallisation rate and the properties of polypropylene.

A promising direction in polymer science and in materials science in recent years has been the development of the principles behind the production of polymer nanocomposites, which are the latest type of functional material and can be used in the most varied spheres of application of plastics. In the modern world, different types of polymer composite based on nanofillers are elbowing out traditional materials and conquering new markets. Here, Shitov et al investigate the processing properties of a composite material based on modified filled polypropylene. Production technology for polymer nanocomposites is not in place, and development of technology is directed towards simplifying, and making less expensive, methods for producing composite materials containing nanoparticles.

The effect of functionalized thin multiwall carbon nanotubes (f-MWCNTs, 2–6 graphene layers) on a rigid epoxy matrix is studied. As a result of f-MWCNT modification, the elastic modulus of the matrix is retained and the ultimate strain and, hence, the strength of the cross-linked polymers increase. According to X-ray diffraction and transmission electron microscopy data, the increase in the strength is related to the f-MWCNT-induced change in the structure of the epoxy matrix.
