Abstract
Changes in the surface of micron-sized melamine-formaldehyde microparticles in dusty structures in a glow-discharge plasma in Ne and Kr were experimentally studied. Microparticles were placed in plasma-dust structures with subsequent extraction. Two effects depending on the exposure time in plasma were established in the experiment: a comprehensive decrease in the particle size and a change in the morphology of their surface. A model was considered, which makes it possible to estimate the contribution of various mechanisms of the interaction of charged plasma particles with the surface of melamine-formaldehyde. The estimates obtained are in good agreement with the experimental data.
