Characterisation of CVD coatings on PEEK substrate
In the frame of a new research study, PEEK substrates were modified by the PTFE + silica/organic silicone multilayer structures.
These were designed via a biomimetic concept based on algae shell structures. The coatings exhibited mechanical wear resistance and ensured adequate human fibroblast cell proliferation. The proliferation was characterised using confocal microscopy.
A complex correlative microscopy characterisation
The analysis together with detailed microstructural characterisation with transmission electron microscopy techniques (TEM) established a complex correlative microscopy characterisation and allowed the determination of the mechanical and biological features of the coatings.
High-resolution TEM (HRTEM) observations revealed possibilities of gas circulation in between the substrate material and the outside environment without making direct contact.
The study is published in: Progress in Organic Coatings Volume 134, September 2019, Pages 244-254.
