In order to obtain a wide-range magnetoelectric (ME) response on a ME nanocomposite that matches industry requirements, Tb0.3Dy0.7Fe1.92 (Terfenol-D)/CoFe2O4/P(VDF-TrFE) flexible films were produced by the solvent casting technique and their morphologic, piezoelectric, magnetic and magnetoelectric properties were investigated. The obtained composites revealed a high piezoelectric response (≈−18...

Past studies with PTFE nanocomposites showed up to 600× improvements in wear resistance over unfilled PTFE with the addition of Al2O3 nanoparticles. Irregular shaped nanoparticles are used in this study to increase the mechanical entanglement of PTFE fibrils with the filler. The tribological properties of 1, 2, 5 and 10 wt.% filled samples are evaluated under a normal pressure and sliding speed...

Epoxy nanocomposites with multiwall carbon nanotubes (MWCNTs) filler up to 0.3%wt were prepared by shear mixing and good dispersion of the MWCNTs in the epoxy was successfully achieved. The electrical behaviour was characterized by measurements of the alternating current (AC) and direct current (DC) conductivities at room temperature. Typical percolation law behaviour was observed with a low pe...

The influence of short-term water absorption on the mechanical properties of halloysite nanotubes-multi layer graphene reinforced polyester hybrid nanocomposites has been investigated. The addition of nano-fillers significantly increased the flexural strength, tensile strength, and impact strength in dry and wet conditions. After short-term water exposure, the maximum microhardness, tensile, fl...

A novel method for preparing epoxy/silver nanocomposites was developed via the in situ formation of silver nanoparticles (AgNPs) within the epoxy resin matrix while using silver nanowires (AgNWs) as a conductive filler. The silver–imidazole complex was synthesized from silver acetate (AgAc) and 1-(2-cyanoethyl)-2-ethyl-4-methylimidazole (imidazole). AgNPs were generated in situ during the curin...

Polymers with good insulating properties are widely used in motors, rotating machines and components in power electronics and microelectronics1-3. It is well know that polymer properties can be greatly improved by adding inorganic fillers to form composite polymer. Polyimide has been a polymer of choice in many areas owing to its excellent dielectric properties, high thermal mechanical strength...

Polymer nanocomposites are known to exhibit enhanced mechanical properties compared to neat polymeric system [1]. Fillers can be used as reinforcement in polymer composites for the enhancement of mechanical properties [2]. Reinforced” polymers consist of a polymeric matrix and relatively stiff filler that exhibit a drastic change in modulus or stress at given strain in compare with the pure pol...

Polyethylene/chrysotile nanocomposites with different amount (0.4 to 6.7 wt%) of filler were prepared by in situ polymerization method using the metallocene Cp2ZrCl2 as catalyst and methylaluminoxane (MAO) as co-catalyst. Previous to polymerization, raw chrysotile was treated by three different methods that used thermal treatment and acid leaching. In method A, raw chrysotile was treated therma...
