The features of photorefractive polymer composites that exhibited stable dynamic properties under continuous operation were investigated. The sample polymer composite materials was based on a bis-triarylamine side-chain polymer matrix with a low ionization potential. The exposure of the grating dynamics was measured to analyze the role of the accumulation of C 60 anions on the dynamic response. The results show that with a 50-ms write-erase cycle at an intensity of 0.5 W/cm 2, these samples can undergo more than 160 000 cycles without any loss in their photorefractive properties.
