Based on the above discussion, we tentatively put forward that the reflectance of PEDOT PSS layer on textured surface is influenced by both the dielectric layer absorption and the surface flatness.
The surface flatness was measured to be 0.32 mm.
The reflectivity, R, is 0.76 (corresponding finesse: 11.4) and the surface flatness is λ/100.
As a typical flexible membrane structure, its dynamic characteristics have great influence on the surface flatness.
Planar membrane antenna performance is directly affected by the surface flatness.
Hence, the surface flatness of this material is superior to the other samples.
On the one hand, it improves the surface flatness of layers of MLMB parts produced by WAAM.
The reflectivity, R, for the OMTI etalon is 0.85 (corresponding finesse: 19.3) and for the American FPIs 0.77 (corresponding finesse: 11) and the surface flatness is λ/100.
There were 16 catenary points distributed on the horseshoe shaped frame to apply stress on the membrane, and the surface flatness was measured to be ± 0.2 mm.
Though the polymerization time increased at the lower temperature of the substrate, the surface flatness of the thin film was improved.
