“…A control over epoxy polymer configuration for brittle rupture behavior, less cracking resistance, and decreased impact strength resulted in decreased toughness. Therefore, epoxy matrix rigidity has been augmented through chemical modification, increased epoxy molar mass, decreased cross‐linking density, adding filler to neat resin, and amalgamation of dispersed toughened phase in epoxy matrix 9 . Data for the effect of fillers' surface chemistry and weight ratio on thermomechanical properties of epoxy composites are compiled in Table 1.…”

Epoxy composites with carbon particles show a range of properties omposite properties are a mixture of intrinsic properties of ingredient phases, so filler contribution in designing composite property intensely relates to volume fraction. Along with that, the interface between matrix and filler plays a vital role in defining the reinforcement mechanism. Filler particles with compatible surface chemistry bring particle–matrix connections on atomic level. Surface chemistry governs the shape of filler either in isolated domains, aggregates, or clusters (group of aggregates), which stem complex orientations. Aggregation may result in poor dispersion of filler that effects its distribution. This diversity of forms makes it feasible to tailor composite properties. This review contains data on both quantitative and qualitative effects of filler on thermomechanical behavior of epoxy composites.

“…[13][14] Electrical studies of composites filled with AgNPs have shown that the percolation threshold can be 10 to 30 vol%, depending on the type of polymer matrix and the technology used to prepare the composites. [15][16][17] However, the size effect in composites with spherical AgNPs was not investigated up to now, despite the fact that such effect is observed in composites with gold nanoparticles. [18] The aim of this paper is to investigate the electromagnetic properties of Ag/PDMS composites with different sizes of Ag particles in wide frequency and temperature ranges.…”

This paper deals with the electrical properties of polydimethylsiloxane nanocomposites filled with Ag nanoparticles (AgNPs) of different sizes. The measurements were carried out over a very broad range of frequencies (20 Hz‐40 GHz), and the results showed that the percolation threshold in the composites is close to 20 vol% and that it is almost independent of particle size. The observed critical exponents reasonably agree with the theoretical values. Above the percolation threshold, the values of dielectric permittivity and electrical conductivity are quite high, ε′ ≈ 107 and σ ≈ 1 S/cm at room temperature and frequency of 129 Hz (which is close to our low frequency limit). The dielectric permittivity of composites decreases strongly with frequency, especially in the microwave range, while the frequency behavior of conductivity strongly depends on the concentration of nanoparticles. Nevertheless, the electrical conductivity and the dielectric permittivity remain high at microwaves (0.1 S/m and 10, respectively), for composites with AgNPs of size 80 to 100 nm at a concentration of 30 vol%.

“…Due to their small size and large surface area to volume ratio, nano particles are unique fillers yielding totally different effects and improved physical properties compared to conventional fillers with sizes in the micrometer range. 3,4 New potential routes have been opened for adhesives and other engineering applications by utilizing nano particles such as nano clays, 5,6 carbon nanotubes, [7][8][9] nano-Al 2 O 3 , 10 nano TiO 2 , 11 nano SiO 2 , 12 amphiphilic copolymers, and other inorganic/ organic nano particles. 13 Boron nitride has been investigated due to its high thermal and low electrical conductivities.…”

The effect of multi-walled carbon nanotube and/or boron nitride nano platelets usage on shear strength and thermal stability of epoxy based adhesives have been investigated. Commercially available diglycidyl ether of bisphenol A based epoxy was used as matrix and reinforced by using nanofillers. The resulting adhesive was tested for its shear-lap adhesion to aluminum alloy sheets (2024-T3). The nano particles modified epoxy adhesives were characterized by Fourier transform infrared, differential scanning calorimetry, and thermal gravity analyses analysis. These characterizations revealed that incorporation of nano particles can result in enhancement in chemical stability. Single lap strength joint testing was conducted in accordance with ASTM-D-1002-10 standard. Fracture morphologies and the effects of multi-walled carbon nanotubes and boron nitride nano platelets on epoxy adhesive were investigated after shear tests by means of scanning electron microscopy. Compared to neat epoxy, increases of 30% in shear strength and 57% in energy required to break joints have been obtained by multi-walled carbon nanotube/boron nitride nano platelet modification.
