| Popis: | A new class of organic conductors, mixed valence DIPS Phi 4 polyiodides, have been used as conductive additives in reticulate doping of polymers. Conductive films have been prepared using three modifications of the reticulate doping technique: a standard one-step method (direct casting), a two-step method consisting of swelling the film containing molecularly dispersed DIPS Phi 4 polyiodides, and a recently developed method in which oxidation of molecularly dispersed DIPS Phi 4 and simultaneous crystallization of its polyiodides in situ is induced by treatment of the pristine film containing the donor with I2/CH2CI2 vapours. The first and the third methods have been found to be the most advantageous. Conductive films with additive concentrations as low as 0.5 wt.% and conductivities of the order of 10-3 S cm-1 were obtained. In all three methods, the best results have been obtained when the conductive network consisted of the most conducting DIPS Phi 4, 2.281 salt. |
