Description
Carbon-based hybrid materials are an important class of artificial materials with potential applications in various fields ranging from energy storage (e.g. harvesting) to recycling applications (e.g. smart debonding). For this reason, both their synthesis process and the assessment of their properties are of high interest. Herein, we present a brief summary of recent developments in the area of functional hybrid materials comprising one-dimensional (1D) carbon allotropes. One of the investigated hybrids are magnesium silicide thermoelectric carbon nanotubes (Mg2Si/CNT) for use as smart flexible n-type thermoelectric materials; these were successfully synthesized through a combined sol-gel and thermal reductive process.
Furthermore, the in-situ growth of CNT-hybrids through chemical vapour deposition process (CVD), was proved to be a facile way to create hybrid materials with unique and interesting properties. In this perspective, the synthesis of hybrid microwave and radiofrequency assisted materials has been investigated, based on metal and ceramic nanoparticles. Synthesis of CNTs on magnetic nanoparticles such as ZnFe2O4 and Fe3O4 was accomplished in a one-step CVD procedure. These hybrids can be used on recycling applications for thermoplastics including carbon fibres, by enabling local heating around the fibre and thus, smart debonding. Also, nanosized silicon carbide has been exploited by utilising the floating catalyst approach, in order to grow SiC/CNT hybrids. The aim for this microwave assisted material is to be incorporated into coatings in a concentration lower than 1 wt. %, in order to provide selective heating on the interphase between the coating and the plastic substrate. By this, smart debonding applications for effective polymers recycling can be achieved.
