Ultraviolet radiation polyimides

Hu Longfei, Li Meishuan, Xu Caihong, Luo Yongming, and Zhou Yanchun. A polysilazane coating protecting polyimide from atomic oxygen and vacuum ultraviolet radiation erosion. Surf. Coat. Technol. 203 no. 22 (2009) 3338-3343. [Pg.295]

Dielectric dissipation factors for polyamides and polyimides increase rapidly on exposure to ultraviolet (290-400 nm) radiation in air [120] short-wave UV radiation (254 nm) has a similar effect on poly(vinylidene chloride) [1658]. Photodegradation of polyethylene rapidly increases both... [Pg.560]

Thesulphonatedpolyimidemembranesarebasedon4,4 -diaminobiphenyl-2,2 -disulphonic acid (BDSA), 4,4 -oxydianiline (ODA), 4,4 -oxydiphthalic anhydride (ODPA) and 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTCDA). The study of the surface properties of fluorinated polyimides exposed to vacuum ultraviolet (VUV) radiation and atomic oxygen may help us understand the stability of these polymers. It will also be interesting to apply this sulphonation method to some novel high molar mass poly-etherimide, as reported by Hsio and Yang (1997). [Pg.16]
