Major advances in the fields of polymer and material science have historically been driven by the aerospace industry.
In response to the requirements of both the commercial and defense aerospace industries, technology has developed from coated fabric and wood to metals and advanced polymer composite systems.
Advanced technologies like electroactive and conductive polymers (EAPs) will be necessary for future systems. These materials’ distinctive properties make it possible to build intelligent systems that respond clearly and predictably to input.
An EAP, for instance, would sense corrosion at the molecular level and release a corrosion inhibitor before major damage could occur as a coating to protect against corrosion. To kill a toxins, a self-detoxifying system would release bactericide upon sensing it.
Due to their unique conductive properties and potential applications in energy storage, sensors, coatings, and electronic devices like organic field-effect transistors, photovoltaic cells, and light-emitting devices, aerospace conductive plastics have gained a lot of attention since they were discovered.
In recent times, these materials have been crucial in making human environments more comfortable. As a result, it is essential to develop novel conjugated conductive materials with high performance.
The development of conjugated conductive materials in various applications and the connection between their chemical structures and performance are discussed in this brief summary. The molecular design and creation of novel conjugated polymer materials with high performance may benefit from this.
The Global Aerospace Conductive plastics market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
For use in aerospace and defense, graphene is used to make plastics that are thermally conductive. Electrical and thermal conductivity of various graphene-based composites, including reduced graphene oxide (rGO), graphene nanoplatelets (GNPs), and carbon nanotube buckypapers (CNT-BP), have been meticulously measured by Tecnalia and Graphenea in Spain.
This research employs a novel technique for embedding whole sheets of graphene into the resin, in contrast to previous work that typically involved dispersing graphene or CNTs in resins.
There are reports of significantly higher values for thermal conductivity, and the proposed manufacturing procedure as a whole makes it possible to produce and process large batches.
According to their conducting mechanism and structural characteristics, Aerospace Conductive plastics can be divided into the following three groups: redox polymer, ionic conducting polymer, and electron conducting polymer.
Free electrons serve as the carriers in electron-conducting polymers, which have a long-conjugated system in the molecular skeleton that results in delocalized electrons.
Thus, they are referred to as conjugated conducting polymers. The energy difference between the full and empty bands should be easily overcome by reducing the energy level difference caused by energy band splitting in order to effectively increase electron movement in the -system.
Due to the ease with which conjugated polymers can be oxidized or reduced, the “doping” technique can be used to alter the distribution state of electrons in the energy band.
