“…Nanocomposites are multi‐phase solid materials in which the fillers have at least one dimension ≤100 nm. Owing to the high surface area to volume ratio of the nano‐sized fillers combined with the quantum size effect, nanocomposite materials often exhibit improved properties compared with their bulk counterparts . Polyacrylamide (PAAM) is a synthetic linear, insulating and polar polymer having (CO‐NH 2 ) groups that have strong interfacial interactions with other polymers and enable the polymer to form hydrogen bonds with drug molecules, facilitating drug diffusion and release .…”

Enhancing the optical, electrical, and mechanical properties of polymeric materials, by blending with another material and doping with nano-fillers, is crucial for improving their performance in optoelectronic, biological, and medical applications. In this work, the influence of adding multiwalled carbon nanotubes (MWCNTs) on the physical properties of carboxymethyl cellulose/polyacrylamide blends is reported. Scanning electron microscopy was used for investigating films' surface morphology and revealed good distribution of MWCNTs on the blend surface. UV-vis-IR spectroscopy showed that absorption and refractive indices, and other dispersion parameters could be controlled by adjusting the films' compositions. Loading 2 wt% MWCNTs narrowed the optical bandgap of the blend from 5.1 to 4.1 eV. Doping with MWCNTs raised the DC conductivity by about two orders of magnitude by forming threedimensional pathways within the blend matrix. The storage modulus increased with MWCNTs loading by 39.3% for the 2 wt% ratio while decreasing with increasing temperature.

“…With increasing fiber content, the coefficient of friction and wear are reduced [6,[32][33][34]. Subsequent fillers use to improve the properties of polyoxymethylene composites are low density polyethylene (LDPE) and wood grain, copper particles or basalt fibers, all of these additives modify POM composites in the direction of develop its strength, thermal, and tribological properties [20,26,27,35,36].In this work, polyoxymethylene composites reinforced with glass fiber (cut roving, with diameter of 10 and 13 µm, and length about 150-200 µm) and carbon fibers (diameter of 7 µm and length about 3 mm) were analyzed. Research showed the effect of used reinforcements on strength properties and behavior of composites under dynamic load.…”

The paper evaluated the possibility of potential reinforcing of poly(oxymethylene) (POM) by glass fiber and the influence of fiberglass addition on mechanical properties under dynamic load. Four types of composites with glass fiber and another four with carbon fiber were produced. The fiber content ranged from 5% to 40% by weight. In the experimental part, the basic mechanical and fatigue properties of POM-based composites were determined. The impact of water absorption was also investigated. The influence of fiber geometry on the mechanical behavior of fiber-reinforced composites of various diameters was determined. To refer to the effects of reinforcement and determine the features of the structure scanning electron microscopy images were taken. The results showed that the addition of up to 10 wt %. fiberglass increases the tensile properties and impact strength more than twice, the ability to absorb energy also increases in relation to neat poly(oxymethylene). Fiber geometry also has a significant impact on the mechanical properties. The study of the mechanical properties at dynamic loads over time suggests that composites filled with a smaller fiber diameter have better fatigue properties.as well as heating fabrics powered by electricity [2][3][4][5]. Many scientific papers present the advantages of introducing carbon fibers to thermoplastic materials. Carbon fibers are not only lightweight or provide very good strength properties, but also have a positive effect on tribological properties, and therefore they also can be successfully used as a reinforcement in ceramic matrices [6][7][8][9][10][11][12][13][14][15][16][17].Carbon fibers are not only one fiber introduced in composites which provide good mechanical properties. Currently, about 60% of produced glass fibers are applied to make composites on polymeric matrices, even though they have insignificantly lower physical and mechanical properties than carbon fibers. Glass fibers are characterized by low elongation and high modulus of elasticity. Attention should be paid to good dielectric properties, namely the fibers have low values of relative permittivity and dielectric loss factor. A valuable advantage of glass fibers is the very good wettability of the polymers, and hence the possibility of forming a strong bond at the polymer/glass interface. The mechanical properties of fiber-reinforced composites improve as the length of reinforcing fibers increase, while the strength of a single glass fiber depends on its diameter. If the fiber diameter is larger, there is a higher probability of material defects and damages describe in literature as micronotches and microcracks [18].Many groups of researchers conduct research on polymer composites with glass fiber. It has been revealed that glass fibers successfully strengthen polymers causing better strength properties, higher resistance to creep, and fatigue, as well as provide greater dimensional stability [19][20][21][22].POM is a thermoplastic material with a high degree of crystallinity. This polymer is obta...

“…Other particles were, for example, nano silica particles addition to enhance strength and thermal properties, or synthetic oil and Teflon particles for better tribological properties. [ 3–10 ] The positive effects of other metal particles such as aluminum, nickel, and silver particles have also been proven. Brostow et al indicated an increase in the strength properties of polyethylene after the introduction of metal particles, however, these properties depended on the quantity.…”

This paper presents an analysis of the hybrid reinforcement of polyoxymethylene composites. Basalt fibers and monocrystalline silicon carbide fibers were used as reinforcement. Basic tests of mechanical properties were carried out, such as the static tensile and flexural test. The tests were repeated under external factors, such as the influence of water aging and a wide range of exploitation temperatures. The materials were also subjected to tribological tests, that is, determination of the friction coefficient and the specific wear rate. Strength tests revealed an increase in the stiffness of the material as well as a reduction the friction coefficient and abrasive wear. The addition of monocrystalline fibers significantly limited water absorption, stabilized the strength properties in the water environment as well as provided better material's resistance to dynamic impact.
