Kinetic regularities of deposition and molecular structure of polyoxymethylene coatings formed from the active gas phase

The kinetic regularities of electron beam dispersion of polyoxymethylene (POM) have been established and the molecular structure of coatings formed by volatile polymer destruction products has been studied. The effect on the coating growth rate, the pressure in the vacuum chamber and the molecular structure of the deposited layers of laser assisted influence and the copper particles introduction into the target were determined. It has been shown that the reactivity of POM dispersion products can be significantly increased by co-dispersing of POM and polyethylene (PE). The deposition of composite coatings occurs at a higher rate. For the POM component of the composite coating, the proportion of folded structures in the volume of the thin layer is significantly higher than the value typical for a single-component POM-based layer.
