Inorganically modified particles FeAl-LDH@SiO ₂ as reinforcement in poly (methyl) methacrylate matrix composite

Abstract

Silica particles were obtained from rice husk to which layered double hydroxide particles were deposited (weight ratio 1 : 1). Fe 2+ -Al 3+ layered double hydroxides (FeAl-LDH) were synthesized by co-precipitation with ratios Fe : Al of 3 : 1 in the presence of SiO 2 particles from the rice husk. Characterization of the synthesized FeAl-LDH@SiO 2 particles was performed by X-ray diffraction, Fourier transforms infrared spectroscopy (FTIR) and scanning electron microscopy with EDS. Prepared FeAl-LDH@SiO 2 particles were used as reinforcing agents in 1, 3 and 5 wt% quantity in poly (methyl) methacrylate matrix. The aim of this study was to examine whether FeAl-LDH@SiO 2 particles affect the mechanical properties of polymer composite materials. The morphology of the composites was examined using a field emission scanning electron microscope. Microindentation, tensile and impact testing determined the mechanical properties of the obtained composites.

Hardness and Wettability Characteristics of Electrolytically Produced Copper Composite Coatings Reinforced with Layered Double Oxide (Fe/Al LDO) Nanoparticles

“…Specifically, the diffraction peaks at 11.7°, 23.7°, 39.4°, and 63.1° are characteristic of the typical layered structure of LDH. These findings from XRD data demonstrate the successful transformation of FeCl2 and aluminium hloralhydrate into the LDH phase, as supported by previous studies [38]. According to XRD data (Figure 2b), the Fe/Al LDO sample consists of ceramic and metal components.…”

2D Layered Nanomaterials as Fillers in Polymer Composite Electrolytes for Lithium Batteries

“…Although not used for PCE preparation, another recent report suggests the compatibility of PMMA and FeAl-LDHs for polymer composite preparation. [182] The compatibility of various LDHs with polymer hosts other than PEO could be exciting for designing better PCEs based on LDH in the future. In line with this, the latest report from Xia et al suggests the prospect of an LDH containing Li + in the crystal structure (LiAl 2 -LDH) for d-PCE preparation (Figure 28a).…”
