CHARACTERIZATION OF ELECTROSTATIC CHARGING OF POLYMERS

Popis výsledku v původním jazyce

The generation of electrostatic charge is the unwanted phenomenon in many technologies and applications including powders and polymers. The goal of this study is to present our initial effort in addressing the electrostatic charge of non-polar polymers,e.g., of compact polyolefin films and of polyolefin powder. We concentrate on effects of: (i) surface roughness, (ii) temperature, (iii) composition of surrounding gas, (iv) charge generation process. Two apparatuses employed in this research are introduced. In the first setup is the polymer sample (powder or film) negatively charged by corona discharge created by high voltage needle electrode. The decay of electrostatic charge is then measured by the ?Field mill? fieldmeter. Results of the electrostatic charge decay measured on different polymer samples acquired by fieldmeter JCI 155 are used to describe influence of the surface morphology, particles size distribution and charge generation process. Triboelectrification is studied by th
