“…To clarify processes connected with the improvement of the electret properties of the polymer materials, it is necessary, first of all, to have sufficiently convincing data on the structure and properties of the filled composite materials. In particular, in the work [44,45] the general state of the problem of preparation and investigation of the composite materials on the basis of polyolefins and mineral fillers is considered. The main perspective directions of preparation, processing and application of the composite materials were shown.…”

“…In the works [46][47][48][49][50], the results of investigation of influence of the standard mineral fillers on basic physical-mechanical and physical-chemical properties of nanocomposites on the basis of comparatively new types of thermoplastic polyolefins -statistic copolymer of ethylene with propylene (REP) and block copolymer of propylene with ethylene (BEP) were presented. It revealed that an introduction of multifunctional structure-forming agentsalizarin and zinc stearate within the ranges of 1.0% mass in the composition of above-mentioned polyolefins improves essentially the strength and rheological characteristics of the composite materials on their basis.…”

The work deals with the results of analytical review of the development and research of polymer composite materials with improved electro-physical and physical-mechanical properties. It found that the selection of special fillers, their variation by quantity and particle sizes in the polymer matrix can essentially affect the electro-conductivity of material and thereby regulate their electret properties on the whole. It revealed that the use of traditional fillers of carbon-black, graphite, minerals, metals, etc. in the composition of thermoplastics, reactoplastics and rubber makes it possible to prepare antistatic products, electromagnetic protective coatings, resistors, various types of current-conducting materials. The use of various lightweight fillers allows preparing lowdensity composites with higher physical-mechanical and electret properties. The spheroplastics based on siloxane elastomer began gaining a larger popularity. There is the data on carbon-blackfilled composite materials based on polyolefins which, at definite ratios, allow preparing the electroconductive products. A certain place in the review is given to the use of highly dispersed metal powders for the improvement of the electret characteristics of composites. Much attention is paid to the investigation of nanofilled composites with the use of large set of the dispersed minerals. The use of hybride polymer nanocomposites opens up new perspectives for their wider use in the production of current-conductive materials. The possibility of chemical binding of mineral filler particles with polymer matrix using the binders with conjugated double bonds provides innovative approaches to the creation of high-strength and heat-resistant electroconductive composites. It becomes obvious that the most perspective direction of preparation of materials with high electret properties must be based on mechanical-chemical synthesis of composite materials.

“…One of the reasons for increase in the relaxing, initial, and quasi-equilibrium stresses of nanocomposites by comparison with unfilled PE, and also a reason for increase in the rigidity of the composites, may be the increase in the degree of crystallinity of the PE when it is filled with nanoparticles. Filler particles may serve as crystallisation nuclei, the presence of which can lead to an increase in the degree of crystallinity of the nanocomposites [8].…”

The effect of nanotubes and nanofibres on the stress relaxation of nanocomposites based on high-density polyethylene (HDPE) was studied. It was found that a very low concentration of multiwall nanotubes (0.1 wt%) leads to a significant increase in the relaxing stresses over the entire period of relaxation. Generalised curves of the relaxation process were plotted, and it was found that the greatest reinforcing effect is rendered by the multiwall nanotubes with the greatest specific surface.

“…These strands were then subjected to air cooling with subsequent pelletisation on a laboratory blade pelletiser. A similar two-stage scheme had been used to achieve the most uniform distribution of nanoadditives in HDPE, which during processing are prone to form aggregates that prevent their uniform distribution in the matrix and thereby do not make it possible to achieve the desired effectiveness during filling of the polymer [8].…”

The effects of nanotubes and modifiers on the elastic modulus and forced elasticity limit of high-density polyethylene were studied. It was found that a very low concentration of multiwalled nanotubes (0.1 wt%) leads to a considerable (twofold) increase in the elastic modulus and a certain increase in the forced elasticity limit. This is connected with the experimentally found increase in the degree of crystallinity of polyethylene when it is filled with the given nanoparticles.
