On the Surface Modification of Melamine-Formaldehyde Particles in Ne and Kr Plasma

Changes in the surface of micron-sized melamine-formaldehyde microparticles in dust structures in a glow-discharge plasma in Ne and Kr are experimentally studied. The microparticles are placed in plasma-dust structures with subsequent extraction. Two effects depending on the exposure time in plasma are established in the experiment: a comprehensive decrease in the particle size and a change in the morphology of their surface. A model is 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.
