Abstract: A kind of polymer film containing dou ble bonds is prepared,which has certain conductivity by means of charge transfer reaction with halogen etc.The polymer is easy to be prepared and machined.Being used as photo polarization conductive film that is one of the most important parts of the new type of so lar battery,its performance changing behavior in space circumstance i.e.under the ir radiation of atomic oxygen and particles with high energy is studied.After investigation on the aging mechanism of the polariz ed film under different preparing and testing conditions methods to impr ove the technique is provided.
