Ultrafast Electro-Thermal Responsive Heating Film Fabricated from Graphene Modified Conductive Materials

Abstract

Flexible electro-thermal heating film has caught great attentions for their efficient energy conversion and easy to customization in many fields. In this work, an ultrafast electro-thermal responsible heating film was fabricated via silk-screen printing method by using graphene modified carbon black based conductive ink. The graphene modified carbon heating film (CHF) was able to reach an equilibrium-state temperature with rapid o o o o heating and cooling rate of 5.6 C/s and 15.6 C/s, comparing to the unmodified sample (1.01 C/s and 1.03 C/s), for the high electrical and thermal conductivity and huge heat exchanging area. The steady temperature of CHF was controllable by changing the amount of graphene. A o dramatic enhancement of steady temperature from 38 to 83 C was controlled by changing graphene amount from 0 to 35 wt.%. The facile fabrication and superior electro-thermal performance of CHF make it feasible to scale up and customization for various heating conditions.

Edge Oleylaminated Graphene as Ultra-Stable Lubricant Additive for Friction and Wear Reduction

“…In this paper, we used ball milling method to exfoliate the graphite powder into edge-carboxylated graphene (ECG) under carbon dioxide atmosphere. [23][24][25][26] The ball milling method has characteristics such as simple preparation process, energy saving and environmental benign for massively production. 27 The ECG was further grafted with the oleophilic oleylamine molecule to prepare edge-oleyaminated graphene (EOG).…”

The Effect of Edge Mode on Mass Sensing for Strained Graphene Resonators

“…Since Geim and co-workers fabricated monolayer graphene by mechanical exfoliation in 2004 [ 1 ], graphene-based device manufacturing infrastructure has seen considerable advancements [ 2 , 3 , 4 , 5 ] due to the excellent mechanical properties [ 6 , 7 , 8 ], preeminent thermal properties [ 9 , 10 ], and tunable electrical performances [ 11 , 12 , 13 , 14 ]. A variety of nanotechnologies have been developed, including thermal interface materials [ 15 , 16 , 17 ]; electromagnetic composites [ 18 , 19 ]; gas separation membranes [ 20 ]; and sensor-based applications [ 21 ], such as accelerometers [ 22 ], biomedical detection [ 23 ], and gas measuring [ 24 ]. Among them, the graphene-based mass sensor has attracted increasing attention with the benefit of its unprecedented atom-thick two-dimensional structure, which provides enough area for the incoming mass flux.…”
