An investigated organic and inorganic reinforcement as an effective economical filler of poly (methyl methacrylate) nanocomposites

Abstract

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.

Broadband dielectric behaviour and structural characterization of PVDF/PMMA/OMMT polymer nanocomposites for promising performance nanodielectrics in flexible technology advances

“…It can be noted from figure 3 that the positions of some IR bands significantly altered, some new bands appeared, and some weak bands either enhanced or suppressed when the OMMT nanoclay was dispersed into the 80PVDF/20PMMA blend host matrix, which all together evidences the composite formation with the polymer-filler interactions. Such changes in these bands positions of the PNC films revealed the formation of interactions primarily between the functional groups of the repeat units in polymer chains and the surface modified nanoclay platelets as reported for some other PNCs [51][52][53]. Besides this notice, the intensities of these IR bands enhanced for the PNC film with 2.5 wt% dispersed OMMT in comparison to that of the 80PVDF/ 20PMMA blend matrix.…”

“…According to the literature [46,50,51], the IR bands which can be assigned to the crystal phases of PVDF are 770 cm −1 (α-phase), 811 cm −1 (γ-phase), 835 cm −1 (overlapped βand γ-phases), 872 cm −1 (γ-phase), 1070 cm −1 (common for both αand β-phase), 1150 cm −1 (α-phase), 1168 cm −1 (β-phase), 1230 cm −1 (γ-phase), 1270 cm −1 (β-phase), 1402 cm −1 (common for both αand β-phase), and 1452 cm −1 (α-phase). In addition to these IR bands of PVDF, the other IR bands at 749, 990, 1434, 1483, and 1729 cm −1 attributed to the vibrational groups of the PMMA structure [46,52]. According to the structural properties of PVDF and PMMA polymeric materials [46,[50][51][52], the FTIR spectrum of semicrystalline PVDF exhibited numerous intense and or weak IR bands at 769 cm −1 (CF 2 skeletal bending), 835 cm −1 (CH 2 rocking/CF 2 stretching), 872 cm −1 (CF 2 stretching), 1070 cm −1 (CH 2 wagging), 1167 cm −1 (CF 2 symmetric stretching), 1230 cm −1 (C−F stretching), 1402 cm −1 (CF 2 symmetric stretching), and 1455 cm −1 (CH 2 scissoring).…”
