Modification and Dispersion of Nanosilica

Journal of Dispersion Science and Technology, 2005
Abstract The modification and dispersion of nanosilica particles were investigated by Fourier transform infrared spectroscopy (FTIR), 29Si CP MAS NMR, thermal gravimetric analysis (TGA), Raman spectroscopy, particle size analysis, transmission electron microscopy (TEM), and dynamic mechanical analysis (DMA) using methacryloxypropyltrimethoxysilane ...

Water Interactions with Hydrophobic versus Hydrophilic Nanosilica

Langmuir, 2018
It is well-known that interaction of hydrophobic powders with water is weak, and upon mixing, they typically form separated phases. Preparation of hydrophobic nanosilica AM1 with a relatively large content of bound water with no formation of separated phases was the aim of this study.

Surface Modification of Nanosilica for PP Composites

Materials Science Forum, 2012
Due to its high purity, favourable surface chemistry and huge specific surface area, fumed silica nanoparticlesare suitable inorganic nanoscopic templates for organic modification and nanocomposite studies. Polypropylene offers good properties with low or moderate cost for many technical applications, such as for solid dielectrics.

Rubber Blend of 80/20 NR/SBR Reinforced with Nanosilica and PS-Encapsulated Nanosilica

Materials Science Forum, 2011
In this study, rubber blend of natural rubber (NR) and styrene butadiene rubber (SBR) at 80/20 NR/SBR was reinforced with nanosilica (nSiO2) and polystyrene-encapsulated nanosilica (PS-nSiO2) in the latex state. The latex of PS-nSiO2 was synthesized by in situ differential microemulsion polymerization using sodium dodecyl sulfate and ...

Characterization of the Waterborne Polyurethane/Nanosilica Composite Synthesized by Dispersing Nanosilica in Polytetrahydrofuran Glycol

Journal of Dispersion Science and Technology, 2012
The waterborne polyurethane/nanosilica composite (PU/SiO2) was prepared by dispersing nanosilica in polytetrahydrofuran glycol (PTMG) and preformed polymer separately. The distribution of nanosilica, mechanical property, thermal performance, and the ultraviolet (UV) absorbance characteristic of PU/SiO2 were investigated by scanning electron microscope,

Experimental and optimization of mechanical properties of epoxy/nanosilica and hybrid epoxy/fiberglass/nanosilica composites

Journal of Composite Materials, 2016
In this paper, the effect of addition of nanosilica on mechanical properties of pure epoxy and epoxy/fiberglass composite has been investigated. The epoxy/nanosilica composites and epoxy/fiberglass/nanosilica hybrid composites have been fabricated, and the Young’s modulus, tensile strength, yield stress and elongation at break have been determined by ...

Dielectric behavior of a ld-polyethylene/nanosilica assembly

2012 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2012
Different LDPE/nanosilica assemblies were imaged in details at nanoscale and some of their dielectric properties were studied. A sol-gel silica coating on polyethylene (PE), very well ordered, resulted into a slight decrease of the real permittivity of the assembly.

Modified Magnetized Water Concrete Using Nanosilica

2020
It is expected that in the near future, the civil engineering community will have to produce structures in harmony with the concept of sustainable development through the use of high-performance materials with low environmental impact that are produced at a reasonable cost. Magnetic water concrete provides one route towards this objective.
