Polyimide materials photodegradation

Low sensitivity in PI decomposition. The reported sensitivity for photodegrad-able polyimide materials was 3-12.7 J/cm for aromatic Pis, when broadband UV light was used [74],... [Pg.32]

Four main mechanisms of the photoalignment are known (i) reversible photochemical trans-cis isomerization in azo-dye-containing polymers, monolayers, and pure dye films (ii) pure photophysical reorientation of the azo-dye chro-mophore molecules (iii) topochemical crosslinking in cinnamoyl side-chain polymers (iv) photodegradation in polyimide materials. [Pg.218]
