“…The authors stated that independent on the Al(OH) 3 content the onset crystallization temperature was 105°C and only 1 wt.% of filler contributed to a certain increase of the crystallization rate. 34 Although there was no change in T c and T m some variation in the composites’ degree of crystallinity was seen. rHDPE-ZrP exhibited a slight decrease but reversely an increase was noticed for rHDPE-Al(OH) 3 and rHDPE-ZrPOct/Al(OH) 3 .…”

Regarding environmental preservation, the upcycling of plastics from petroleum source is a consistent alternative. This work intended to investigate melting extruded composites of post-consumer HDPE (rHDPE) filled with pristine zirconium phosphate (ZrP), aluminum hydroxide [Al(OH)3] and aluminum hydroxide modifying-zirconium phosphate [ZrPOct/Al(OH)3]. Physico-mechanical and flame retardancy were assessed. FTIR revealed that rHDPE brought some degree of oxidative degradation probably from its cleaning process and/or processing. By nuclear magnetic resonance at time domain, rHDPE showed three relaxation domains. Fillers induced the lowering of rHDPE relaxation time owing to polymer/filler by hydrogen bonds. Diffraction pattern of rHDPE/Al(OH)3 and rHDPE/ZrPOct/Al(OH)3 indicated better fillers’ dispersion. Fillers changed rHDPE crystallinity degree and thermal stability but rheologic properties were invariable. For all composites, elastic modulus increased (up to 17%) indicating stiffening. Yield strength did not change but stress and strain at break decreased. For the composites, SEM/EDS showed better dispersion and distribution of ZrP and ZrPOct/Al(OH)3 particles. It was assumed that ZrP and ZrPOct/Al(OH)3 greatly increased the flame retardancy. The work corroborates the importance of polymers’ upcycling, and it is in consonance with the objectives of 2030 Agenda released by United Nations.

“…The obtained data show the possibility of reprocessing of nanocomposites by methods of high-speed molding under pressure. It has been shown by a method of scanning electron microscope that an introduction of the coppercontaining nanofillers into polypropylene/ethylene-propylenediene elastomers leads to the formation of finely spherulitic layered structure of filled composition and thereby improvement of fluidity and rheological properties [61].…”

The physical-mechanical, thermophysical, and other important properties of polymer composites primarily depend on the polymer fillers used as modifiers. Examples of fillers include substances that act as structural modifiers, additives, mineral additives, and so on. As studies conducted in this area show, modifiers for various purposes are used to improve chemical and physical-mechanical parameters. The article provides information about the development and production of polymer composite materials. The possibility of obtaining and using composite materials in various fields of technology is shown. In addition, a review of studies that provide a broad understanding of polymer composite materials is also collected. It has been shown that the use of polymer composite materials can lead to significant advances in modern manufacturing. The article also provides information on or-ganic and inorganic fillers with different properties. Based on this, the results of studies carried out in the direction of obtaining polymeric materials using carbon, carbon graphite, fiberglass, etc. are summed up. The nanocomposites of the new generation demonstrate innovative results. This paper shows innovative applications of polymer composite materials for various purposes. All this makes it possible to use the rich mineral resources of Azerbaijan in the production and operation of polymer composite materials
