“…Production of polymer-based materials requires mining and extracting petroleum resources [ 1 ], and during their service life, these products are degraded and emit harmful or environmentally burdening products. Increasing pollution of the natural environment and depletion of global oil and coal deposits force the industry to search for and develop new, more sustainable, and low-energy polymer materials [ 2 , 3 , 4 ]. This goal can be achieved through the use of biopolymers and biodegradable materials (e.g., bio-polyethylene (BPE) [ 5 ], poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) [ 6 ], polylactide (PLA) [ 7 ]), and/or the production of polymer composites with fillers of natural origin using, for example, natural fibers [ 8 , 9 , 10 ], lignin [ 3 , 11 ], or natural powder fillers [ 12 , 13 , 14 ].…”

The Accelerated Aging Impact on Mechanical and Thermal Properties of Polypropylene Composites with Sedimentary Rock Opoka-Hybrid Natural Filler

This paper presents the impact of accelerated aging on selected mechanical and thermal properties of isotactic polypropylene (iPP) composites filled with sedimentary hybrid natural filler-Opoka rock. The filler was used in two forms: an industrial raw material originating as a subsieve fraction natural material, and a rock calcinated at 1000 °C for production of phosphorous sorbents. Fillers were incorporated with constant amount of 5 wt % of the resulting composite, and the material was subjected to accelerated weathering tests with different exposition times. The neat polypropylene and composites with calcium carbonate as a reference filler material were used for comparison. The aim of the research was to determine the possibility of using the Opoka rock as a new hybrid filler for polypropylene, which could be an alternative to the widely used calcium carbonate and silica. The thermal, mechanical, and structural properties were evaluated by means of differential scanning calorimetry (DSC), tensile tests, scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy with attenuated total reflectance (FTIR/ATR) prior to and after accelerated aging. As a result, it was found that the composites of polypropylene with Opoka were characterized by similar or higher functional properties and higher resistance to photodegradation compared to composites with conventional calcium carbonate. The results of measurements of mechanical properties, structural and surface changes, and the carbonyl index as a function of accelerated aging proved that Opoka was an effective ultraviolet (UV) stabilizer, significantly exceeding the reference calcium carbonate in this respect. The new hybrid filler of natural origin in the form of Opoka can therefore be used not only as a typical powder filler, but above all as a UV blocker/stabilizer, thus extending the life of polypropylene composites, especially for outdoor applications.

“…The biodegradability property for polymer-filler composites was assumed on the basis of the available literature concerning the above topic. The research described in the paper did not carry out additional biodegradation studies, and adopted a general thesis based on studies such as [ 47 , 48 ]. In the paper, we may have concluded too quickly that typical biological degradation would be obtained, and we were generally concerned with degradation, that is, the design and development of a product that, due to the need to protect the environment, is not made in 100% of plastic, but is filled to a large extent with a biological filler.…”

Modification of the Properties of Polymer Composites in a Constant Magnetic Field Environment

et al. 2021

In this paper, polymer composites based on polylactide (PLA) and epoxy resin (Epidian 5) were studied in terms of the influence of magnetic induction on their changes in physicochemical properties. The composites contained admixtures in the form of magnetite (Fe3O4) and crystalline cellulose (Avicel PH-1010) in the amount of 10%, 20%, and 30% by weight and starch in the amount of 10%. The admixtures of cellulose and starch were intended to result in the composites becoming biodegradable biopolymers to some extent. Changes in physical and chemical properties due to the impact of a constant magnetic field with a magnetic induction value B = 0.5 T were observed. The changes were observed during tests of tensile strength, bending, impact strength, water absorbency, frost resistance, chemical resistance to acids and bases, as well as through SEM microscopy and with studies of the composition of the composites that use the EDS method and of their structure with the XRD method. Based on the obtained results, it was found that the magnetic induction value changes the properties of composites. This therefore acts as one method of receiving new alternative materials, the degradation of which in the environment would take far less time.

“…In contrast to the current study, in most of the earlier research work carried out on polymer/lignin blending, a significant reduction has been reported in elongation at break and, consequently, in toughness on increasing the bio-filler content even for surface-treated lignin particles. This behavior has been attributed to the reduced mobility of the polymer chains obtained by the strong filler-filler interactions and incorporation of rigid lignin moiety in the matrix that caused the composites to become more brittle [19,30]. It has also been ascribed to the aggregation of the lignin particles due to polar functional moiety in the lignin structure, resulting in poor compatibility between the components [11,51].…”

“…This high carbon content material is being extensively used as a reinforcement material for polymer biocomposite production due to its abundant availability, sustainability, biodegradability, rigidity, and adequate thermal stability, as well as antibacterial and anti-oxidating activity [16][17][18]. Furthermore, it has been reported that using lignin as a filler reduces material costs [19,20]. Nevertheless, due to the hydrophobic nature of polyamides as well as the relatively less hydrophobic behavior of lignin arising from surface hydroxyl groups, the compatibility between the components would be somewhat challenging.…”
