제목 In-situ Fabrication of Vitrimer-CNT Composites for Highly Sensitive Temperature-Resistance Sensor
초록 Carbon nanotube (CNT) is one of the most well-known conducting carbon materials which can provide electrical property and enhance mechanical property to polymer matrix. Despite of these advantages, difficulty of well dispersing CNTs due to bundling caused by van der Waals interaction between tube surfaces makes it hard to applicate CNTs instantly. Ultrasonication assisted exfoliation, the most well-known process, requires long time, multi-step process, and toxic organic solvents to fabricate polymer-CNT composites. Here, we suggest quick mechanical fabrication of vitrimer-CNT composites through simple grinding with an aromatic molecule and demonstrate its highly sensitive temperature-resistance sensing properties.
