제목 Vitrimer-CNT Composites for Highly Sensitive Temperature-Resistance Sensor
초록 A potential of carbon nanotubes (CNT) based on excellent mechanical and electrical properties makes CNT as one of the most promising material for electrical applications. To obtain sufficient performance with CNT composite, CNT should be well dispersed in main body. Exfoliating CNT by ultrasonicating in solvent is the most widely used but it has some challenges to be solved (long time, multistep process including melting polymers and drying solvents, toxicity of those organic solvents). Here, we suggest in-situ mechanical fabrication of vitrimer-CNT composites without using any organic solvent and demonstrate further application as a flexible highly sensitive thermistor. By simple grinding CNT with an aromatic molecule, we could sufficiently dispersing CNT and short time in-situ fabrication of vitrimer-CNT within 1.5 hours, which is time and cost-efficient process.
