“…This indicated that the interactions between the fibers and the matrix were strong enough to allow load transfer from the matrix to the fibers, which should ensure better mechanical properties of the processed hybrid nanocomposite [41, 42]. The interfacial adhesion strength between the matrix and the fibers affected the impact property of composites and resistance to crack generation and propagation [65–69]. These failure mechanisms led to the high absorption of impact energy as a consequence of dissipation during crack propagation.…”

The processing and characterization of hybrid PMMA resin composites with nano-zirconia (ZrO2) and electrospun polystyrene (PS) polymer fibers were presented in this study. Reinforcement was selected with the intention to tune the physical and mechanical properties of the hybrid composite. Surface modification of inorganic particles was performed in order to improve the adhesion of reinforcement to the matrix. Fourier transform infrared spectroscopy (FTIR) provided successful modification of zirconia nanoparticles with 3-Methacryloxypropyltrimethoxysilane (MEMO) and bonding improvement between incompatible inorganic nanoparticles and PMMA matrix. Considerable deagglomeration of nanoparticles in the matrix occurred after the modification has been revealed by scanning electron microscopy (SEM). Microhardness increased with the concentration of modified nanoparticles, while the fibers were the modifier that lowers hardness and promotes toughness of hybrid composites. Impact test displayed increased absorbed energy after the PS electrospun fibers had been embedded. The optimized composition of the hybrid was determined and a good balance of thermal and mechanical properties was achieved.

“…Figure 5 shows the OM of the surface of the films, which allowed the visualization of the distribution of C30B particles in the PLA matrix of the PLA/C30B films. Obtaining a homogeneous dispersion of the material used as reinforcement is one of the most important requirements to improve the properties of polymer/clay materials [87]. The neat PLA sample (Figure 5.a) presented a smooth surface without voids or bubbles; however, some impurities were visualized.…”

Poly (Lactic Acid) (PLA) is considered one of the most promising polymers. However, neat PLA films have limitations. An effective strategy to overcome these problems is incorporating clay or essential oils. Cloisite 30B (C30B) is an organoclay widely used to improve the properties of polymers. Notably, the development of films incorporating Oregano Essential Oil (OEO) has attracted significant attention. Compression molding manufactured neat PLA, PLA/C30B, and PLA/C30B/OEO films in this manuscript. The visual evaluation indicated that the films had a good surface finish, and the films thickness varied between 0.15–0.19 mm. The moisture content increased with the incorporation of C30B and OEO. Optical microscopy showed a good distribution of clay particles. The transparency of the films increased with OEO, while with C30B, it presented greater opacity. Incorporating C30B/OEO in the PLA matrix is a promising film proposal that can be directed to the packaging sector. However, other analyses must be done better to understand the films performance for such an application.

“…Many research works suggested that addition of inorganic nanofiller into the polymer deals with the enhancement of polymer properties, which greatly differ from the conventional polymer ones exhibit unexpected properties. [7][8][9] On the other hand, the PVDF is a polar polymer with excellent properties, usually used blended with other polymer in order to improve some properties 10 or with the clay as nanocomposites. 11 The main challenge in the preparation of nanocomposites is the nanoparticules dispersion.…”

In this study, a comparative study of nanocomposites with treated and untreated metal oxide nanoparticules using a plastograph was investigated. Stearic acid and co-mixing technique were chosen as a fast technique to ensure the dispersion of the filler into the polymeric matrix. Fillers were mechanically treated and co-mixed with stearic acid using kitchen coffee grinder and the mixture was then added to the polymeric matrix in a Brabender plastograph with various contents of 0.5 wt. %, 1 wt. % and 2 wt. %. The method effectiveness has been proved by AFM analysis. The results showed that the incorporation of inorganic semiconductor nanoparticles into polymeric matrix improves the dielectric properties. Results showed that with the co-mixing process and stearic acid the inorganic nanofillers have a strong influence on the permittivity of resulting nanocomposites.
