Recent Progress, Challenges, and Trends in Polymer-Based Sensors: A Review

Abstract

Polymers are long-chain, highly molecular weight molecules containing large numbers of repeating units within their backbone derived from the product of polymerization of monomeric units. The materials exhibit unique properties based on the types of bonds that exist within their structures. Among these, some behave as rubbers because of their excellent bending ability, lightweight nature, and shape memory. Moreover, their tunable chemical, structural, and electrical properties make them promising candidates for their use as sensing materials. Polymer-based sensors are highly utilized in the current scenario in the public health sector and environment control due to their rapid detection, small size, high sensitivity, and suitability in atmospheric conditions. Therefore, the aim of this review article is to highlight the current progress in polymer-based sensors. More importantly, this review provides general trends and challenges in sensor technology based on polymer materials.

On the Use of Polymer-Based Composites for the Creation of Optical Sensors: A Review

“…Measurement and control of the composition of aquatic environments, soil and air, as well as the quality assurance of various products produced by human is impossible without the use of analytical systems, and their improvement is a necessary permanent task. The latest trend is the development of smart materials that respond to given influences from external sources through physical or chemical reaction, which leads to a change in the characteristics of the material [ 1 ]. The smart polymer-based materials play an increasingly important role [ 2 ].…”

“…Polymer-based sensors are of increasing interest because the ingredients used could be easily processed and could be matched for biocompatibility [ 5 , 6 , 7 ]. The steady increase in publications on the topic and investment in this area of research are proof that such technologies are among the most promising at the moment [ 1 , 8 ]. Conducting polymers, hydrogels, molecularly imprinted polymers (MIP), and composites and nanocomposites are the common polymer-based materials used in sensing devices [ 9 , 10 , 11 , 12 ].…”

“…and makes it possible to detect target analytes [ 16 , 17 ]. Another important advantage of polymer-based sensors is the ability to tune their physical/chemical properties so that their resistance to degradation, biodegradability and flexibility can be modified [ 1 , 18 ]. The increasing opportunities for recycling and upcycling of polymers should also be mentioned [ 19 , 20 ].…”

Experimental and Computational Approaches to Sulfonated Poly(arylene ether sulfone) Synthesis Using Different Halogen Atoms at the Reactive Site

“…The field of polymer chemistry has advanced significantly over the past few decades [9][10][11][12][13][14]; however, polymer synthesis is based on traditional material development methods that rely on the experience of researchers. To synthesize a polymer with the desired properties, it is necessary to find appropriate reactants, such as monomers, solvents, and reagents, and proceed with an appropriate synthetic methodology.…”

Studying the Conductivity Effect of Polythiophene / Polypyrrole / Polyaniline (PT /PPY /PANI) Deposition on Indium Tin Oxide (ITO) Glass

“…Prosedur ini digunakan bagi memperolehi filem nipis ultra dengan struktur dan ketebalan yang dapat dikawal pada peringkat molekul . Filem LB berasaskan polimer konduksi banyak digunakan dalam biopengesan seperti dalam pengesan ion, pengesan optik dan sebagai peralatan elektronik molekul (Alam et al 2022). Sifatnya yang unik seperti mempunyai kestabilan dalam proses redoks kimia, mempunyai muatan kapasiti yang tinggi, mempunyai kestabilan terhadap suhu persekitaran dan mempunyai sifat elektrokimia yang baik telah menjana kepada aplikasi polimer yang lebih berkesan (Dhawan et al 1997).…”
