چکیده

The effect of titanium dioxide as a semiconductive additive and barium titanate as a highly polar additive on the d.c. transient currents in low density polyethylene is investigated. Experiments were made using thick specimens under high electric field ( > 25 x 106 V/m) and constant temperature of 40OC. Results indicate that the incorporation of the foresaid additives has a remarkable effect on the d.c. transient currents in low density polyethylene.

Molecular Dynamics Studies on the Dispersion of Silica Nanoparticles in Polyethylene Melt Using a Coarse-Grained Model

Particles are important additives for altering and enhancing the properties of polymers. When the particle size approaching the fundamental length scale of the material, new mechanical, optical, and electrical properties arise, which are not present in the conventional macroscopic counterpart. For example, the dielectric constant of a polymer fluid can be increased by addition of ceramic nanopa...
