- Abstract
An azo chromophore 4-[(6-nitrobenzothiazole-2-yl)diazenyl]phenyl-1,3-diamine NBDPD was synthesized with 2-amino-6-nitrobenzothiazole and m-phenylenediamine by diazo-coupling reaction. Then, NBDPD was polymerized with NJ-220 and IPDI to obtain novel azo benzothiazole polyurethane-urea (BPUU). The structure and physical properties were characterized and investigated. The refractive index and transmission loss of BPUU film were measured by attenuated total reflection technique and the CCD digital imaging devices. The polymeric digital optical switch (DOS) based on the thermo-optic effect of the BPUU was designed and simulated. The results showed that the power consumption and response time of the DOS could be only 2.3 mW and 5.0 ms, respectively.
