Special Issue Information

Dear Colleagues,

Functional organic materials have attracted enormous interest since they are generally accepted by the international community of researchers in the natural, medicinal and technical sciences as drivers of technological and societal progress. Due to their unique intrinsic optical, electrical, mechanical, photoelectric, photocatalytic and chemical/physical sensing properties, there are a number of application fields in which they can be used in form of thin films, rods, wires, nanomaterials or bulk materials. Aspects such as low weight, functional flexibility, simple processability, easy tunability of chemico-physical properties, and environmental friendliness are very much in demand in modern chemistry that seeks to positively impact our daily lives. Functional organic materials match all these features, which can be properly addressed starting from synthesis up to the final applications. The interdisciplinary approach is fundamental to achieve progress, since the quality and performance of organic materials have to match both the chemico-physical properties required for their application and the requirements for the engineering of the final device. As a consequence, the structure–properties correlation study is also a key step in the research into new functional organic materials with enhanced properties. The aim of the present Special Issue is to cover the most recent advances in functional organic material research, including design, synthesis, characterization, chemico-physical properties, theoretical study, applications and device performance in all fields in which they can be usefully employed.      

Researchers are cordially invited to share their outstanding achievements and submit a paper to this Special Issue.

Polymers mixed with conductive fillers hold significant potential for use in stretchable and wearable sensor devices. Enhancing the piezoresistive effect and mechanical stability is critical for these devices. To explore the changes in the electrical resistance under high strains, typically unachievable in single-layer composites, bi-layer structures were fabricated from carbon nanotubes (CNTs) and EcoFlex composites to see unobservable strain regions. Spherical types of non-conductive fillers composed of polystyrene and conductive filler, coated with Ni and Au on non-conductive fillers, were used as secondary fillers to improve the piezoresistive sensitivity of composites, and their respective impact on the conductive network was compared. The electrical and mechanical properties were examined in the static state to understand the impact of these secondary fillers. The changes in the electrical resistance under 100% and 300% tensile strain, and their dependence on the inherent electrical properties of the secondary fillers, were also investigated. Single-layer CNT composites proved incapable of withstanding 300% strain, whereas the bi-layer structures proved resilient. By implementing cyclic stretching tests, contrary to non-conductive fillers, reduced piezoresistive influence of the conductive secondary filler under extreme strain conditions could be observed.
