Paper Abstract

Optical, dielectric, thermal, physico-mechanical properties of new fluoro-containing alicyclic polyimides were investigated. High optical transparency in visible and UV ranges of the films with thickness 10-25 μm, which lower boundary was registered at 125-260 nm; as well as reflectivity index being 1.492-1.515 were recorded. Dielectric permeability was characterized with low rates and stability up to 300 °С depending on chemical structure. Polyimides were stable with heating in air up to 320-380 °С. Prepared films show break tensile at 145 MPa with elongation up to 50% due to the excellent film-forming properties. Films based on polyimides with polyaniline composition demonstrates reflectivity index 1.60.
