Conjugated polymers are intriguing materials that have potential practical applications in diverse interdisciplinary subjects. Among them, polydiacetylenes (PDAs) have been extensively studied due to their interesting structural, spectral, and optical features. In particular, the unique colorimetric and fluorescent transition of PDAs in response to different external stimuli makes them a novel class of sensing materials, and numerous applications of PDAs as bio-or chemosensors have been explored in the past few decades. In this review, we summarize the latest developments with regard to the applications of PDAs as a class of sensing materials presented in the literature since 2014. This review is sorted into categories based on the structural differences of diacetylene monomers, from which PDAs are generated. In addition, different forms of PDAs and various methods for improving the sensing performance of PDAs are also emphasized.

“…The vibration absorption peak of the carboxy group in the MWCNTs-COOH at about 3400 cm −1 and 1646 cm −1 are smaller than that of BaTiO 3 /MWCNTs (figure S3). This is due to the formation of covalent bonds between amino-modified BaTiO 3 and carboxylated MWCNTs through condensation reactions [33][34][35]. The XRD patterns of BaTiO 3 /MWCNTs with different BaTiO 3 demonstrate the main crystal phase of BaTiO 3 /MWCNTs belongs to the BaTiO 3 phase (figure S4) [36].…”

The piezoelectric constant of polyvinylidene fluoride (PVDF) is inferior to that of piezoelectric ceramics, which will impede the efficient application in smart systems. In this work, we modulated the content of BaTiO3/multi-wall carbon nanotubes (MWCNTs) in the BaTiO3/MWCNTs/PVDF electrospun nanofibers to facilitate the β phase formation in the PVDF to enhance the piezoelectric properties of BaTiO3/MWCNTs/PVDF films. The BaTiO3 combined with MWCNTs through chemical bands can enhance the electrostatic interaction at the vicinity of BaTiO3-PVDF interface to induce augmentation of the local conformational disorder and result in the enhanced nucleation and stabilization of β phase in the BaTiO3/MWCNTs/PVDF films. When the ratio between BaTiO3 and MWCNTs is about 3:1, the PVDF-BM-3 can deliver the output voltage of 39.5 V under 250 kPa with a frequency of 10 Hz. The PVDF-BM-3 electrospun nanofibers as triggers used in the wireless alarm system can achieve comparable sensitivity under different external stresses. This work paves a new promising pathway for self-powered piezoelectric sensors in the Internet of Things.

Conjugated Copolymers through Electrospinning Synthetic Strategies and Their Versatile Applications in Sensing Environmental Toxicants, pH, Temperature, and Humidity

Conjugated copolymers (CCPs) are a class of polymers with excellent optical luminescent and electrical conducting properties because of their extensive π conjugation. CCPs have several advantages such as facile synthesis, structural tailorability, processability, and ease of device fabrication by compatible solvents. Electrospinning (ES) is a versatile technique that produces continuous high throughput nanofibers or microfibers and its appropriate synchronization with CCPs can aid in harvesting an ideal sensory nanofiber. The ES-based nanofibrous membrane enables sensors to accomplish ultrahigh sensitivity and response time with the aid of a greater surface-to-volume ratio. This review covers the crucial aspects of designing highly responsive optical sensors that includes synthetic strategies, sensor fabrication, mechanistic aspects, sensing modes, and recent sensing trends in monitoring environmental toxicants, pH, temperature, and humidity. In particular, considerable attention is being paid on classifying the ES-based optical sensor fabrication to overcome remaining challenges such as sensitivity, selectivity, dye leaching, instability, and reversibility.
