Abstract
- • A novel CNF/rGO aerogel with supporting column and 2D layered structure was prepared. • CNF/rGO aerogel film with low loading has efficient thermal management performance. • Thermal conductivity of CNF/rGO aerogel with 1 wt.% rGO can reach upto 16.304 W/m K. • The CNF/rGO aerogel film shows potential for emergent energy storage devices. Cellulosic materials are especially suitable for use in flexible electronic products because of their light weight, good tolerance, flexibility, and biodegradability. In this work, cellulose nanofibril/reduced graphene oxide (CNF/rGO) nanocomposites are prepared and the thermal properties of the nanocomposites are analyzed. A supporting column and 2D layered structure porous paper is obtained with CNF/rGO as the heat conduction skeleton, which shows excellent thermal conductivity. The results show that this novel CNF/rGO porous paper has an ultrahigh in-plane thermal conductivity of up to 16.30 W/m K when only 1 wt.% rGO is added in, demonstrating efficient thermal management performance of the CNF-based nanocomposites with low rGO loading. We believe that the development of thermal management techniques using CNFs and rGO for emergent energy storage devices will lead to efficient technologies, further easing our daily lives.
