Mechanical properties of epoxy composites reinforced with a low volume fraction of nanosilica fillers

Structure Analysis of Fe3O4@SiO2 Core Shells Prepared from Amorphous and Crystalline SiO2 Particles

“…The 3014-3498 cm -1 wavenumbers show O-H (water molecule) bond stretching in SiO2. Such functional groups have similarities with the characteristics of the Fe3O4@c-SiO2 particles obtained from the previous research [25], [26]. [31] According to the results of functional groups adjustment of the Fe3O4@a-SiO2 particles as shown in Table 2, there is a bending vibration on the Si-O bond at the wave number of 468 cm -1 .…”

“…Typically, the SiO2 nanoparticle has an amorphous phase, and it can be commercially produced as silica gel, fume-silica, and so forth. Several applications of SiO2 nanoparticles for examples such as medical purposes [22][23][24], as additives for rubber and plastics [25][26][27], as fillers for composite construction concrete [28][29][30], as stabilizers and agents drug delivery and theranostics [23,31], and as a heavy metal absorbent material in a water filter [14], [22].…”

Synergistic Effects of Mixed Silica Micro-nanoparticles on Compressive Dynamic Stiffness and Damping of Epoxy Adhesive

“…Welldispersed silica nanoparticles stiffen and toughen an epoxy adhesive more efficiently than silica microparticles owing to their larger surface-to-volume ratio, forming a more substantial matrix-filler interface area at a given weight fraction [1][2][3][4][5][6][7]. However, without any treatment, high-silica-content nanoparticles are difficult to disperse uniformly using a conventional mechanical mixer and tend to aggregate/agglomerate in the epoxy matrix [8][9][10].…”

Corrosion resistance of superhydrophilic and superhydrophobic TiO2/epoxy coatings on AISI 316L stainless steel

“…3,4 However, to avoid their susceptibility to abrasion 5 and poor resistance to crack propagation, due to a highly cross-linked structure, 6 the basic idea is to enhance the mechanical properties and to promote the surface compatibility of the coating by incorporating different nanofillers. [7][8][9][10][11][12][13][14][15][16] It is mainly the favourable effects of the particle size, the volume fraction and the size distribution on the mechanical properties of composite coatings that have been studied.
