Abstract

The novel 0.6 wt% 3,4-dimethoxy-styrene-3-methylbenzothiazole p-toluene sulfonate (DOBT)−polyvinyl alcohol (PVA) binary composite film based flexible sensor is fabricated in this work, and its piezoelectric and third-order nonlinear optical absorption properties are investigated through using linear motor and femtosecond open-operture Z-scan technique, respectively. Piezoelectric measurements indicate that this sensor exhibits desirable piezoelectric properties with an open-circuit voltage of 1.75 V and a short-circuit current of 57.10 nA under an external compressive force of 10 N at 1 Hz. Z-scan traces reveal when irradiated by a 520 nm laser beam, this sensor with a linear transmittance of 94.0% can exhibit remarkable optical limiting performances. In particular, both the piezoelectric and third-order nonlinear optical limiting responses that observed from this sensor originate from the ionic organic molecule DOBT alone, suggesting a promising application prospect of new DOBT in the fields of piezoelectricity and nonlinear optics. These results together establish an experimental foundation for applications of 0.6 wt% DOBT−PVA binary composite film based flexible sensor in sustainable self-powered and high-energy laser protection systems in the future.
