Biomimetic Functional Fluorinated Oxygen-Containing Coatings on 3D-Printing Composite Polymer Items

Year: 2025

Type: article

Abstract: We manufactured the 3D-printed prototypes with increased wear resistance using a combination of the following: biomimetic design (the shark skin was used as a natural object to follow), 3D-printing technological parameter regulation, rational choice of polymer matrix, dispersed filling ingredients and items' surface gas-phase modification technique. It was established that the bulk modification of the PETG filament with montmorillonite, graphite nano-plates, and other ingredients can reduce the 3D-printed prototypes' wear by up to eight times. The gas-phase fluorination of the product's surface provides a decrease in the rest friction coefficient and temperature in the "indentor-3D-printed disk" contact pair. We obtained the texture models and quantified the degree of similarity between the shark skin and the 3D-printed prototypes' surfaces.
