Polymer matrix composites have garnered the interest of the dentistry sector. Nano-fillers are frequently used as reinforcements in these composites to enhance their characteristics. Poly (methyl methacrylate) was filled with date seed nanoparticles (DSNP) and titanium oxide nanoparticles (TiO2NP). In this work, two nanofillers (DSNP and TiO2NP) were analyzed using Fourier-transform infrared spectroscopy (FTIR). In addition, the features of the PMMA-nanofiller composite were experimentally evaluated via compression, micro-hardness, wear rate (WR), and coefficients of friction (µ) testing. Utilizing a scanning electron microscope (SEM), the microstructure of the PMMA-DSNP composite was examined. The results of the experiments on the nanocomposites demonstrated that the elastic modulus, microhardness, wear resistance, and friction resistance increased with an increase in DSNP content to 1.2 wt, in comparison to TiO2NP at the same concentration. Finally, according to the guidelines, the ideal weight was determined to be 1.2 wt%, filler in the form of DSNP, at a normal load of 10 N.

In the last few decades, there has been an increasing demand for low-cost raw materials and environmentally eco-friendly end products. This demand stimulated a growing interest in natural particles as potential reinforcement materials for composite manufacturing. In this paper, we introduce organic date-seed nanofillers (DSN) as reinforcement materials for the development of enhanced polymer nanocomposites. We particularly investigate the effect of these nanoparticles on two types of polymer base materials, namely medium-density polyethylene (MDPE) and polyethylene terephthalate (PET). A collection of MDPE and PET nanocomposite samples with DSN content ranging from 0.0–0.75 wt% has been prepared using a hot compression method. The MDPE-DSN and PET-DSN nanocomposite structures were analyzed using a scanning electron microscope (SEM), energy-dispersive X-ray analysis (EDXA), and Fourier-transformed infrared spectroscopy (FTIR). The mechanical characteristics of these nanocomposites were experimentally examined through wear loss and Vickers micro-hardness tests. The experimental results show that the MDPE-DSN composite is chemically more stable than the PET-DSN one. Moreover, the MDPE-DSN nanocomposite shows enhanced hardness and wear resistance properties, while the PET-DSN one shows less noticeable enhancements. The best enhancements were obtained with a DSN reinforcement of 0.75 wt%., and a normal load of 10 N. As well, the experimental outcomes show a good agreement with theoretical predictions. In general, the DSN material enhances the mechanical properties of polymer materials and reduces their economic costs.

“…Therefore, the values of tensile strength of TPVs significantly reduced with the increase of impregnation of epoxy resin. All the same, the tensile strength of TPV 8 still reached 67 MPa, which is significantly higher than the values of the transparent plastic substrates used in flexible electronic devices (such as polyethylene terephthalate, whose the tensile strength is around 50 MPa [43]).…”

In this work, poplar veneer (PV) rotary-cut from fast-growing polar was delignified to prepare flexible transparent poplar veneer (TPV). Lignin was gradually removed from the PV and then epoxy resin filled into the delignified PV. The study mainly concerns the effect of lignin content on microstructure, light transmittance, haze, tensile strength, and thermal stability of the PVs impregnated with epoxy resin. The results indicate that the lignin could be removed completely from the PV when the delignification time was around 8 h, which was proved by FTIR spectra and chemical component detection. Moreover, according to SEM observation and XRD testing, the porosity and crystallinity of the PVs were gradually increased with the removal of lignin. Also, the optical properties measurement indicated that the light transmittance and haze of the TPVs gradually increased, and the thermal stability also became more stable as shown by thermogravimetric analysis (TG). However, the tensile strength of the TPVs declined due to the removal of lignin. Among them, TPV8 exhibited excellent optical properties, thermal stability, and tensile strength. Consequently, it has great potential to be used as a substrate in photovoltaics, solar cells, smart windows, etc.
