Graphene Membrane Forms a Soft, Stretchable Wearable Heater ACS_AMI nanomaterials materials
By Bhavna KavetiOct 14 2022Reviewed by Susha Cheriyedath, M.Sc. Wearable heaters are highly desirable for low-temperature environments. However, the fundamental challenge in achieving such devices is to design electric-heating membranes with flexible, breathable, and stretchable properties.
The temperature increased to 69.7 degrees Celsius when a voltage of 36 volts was applied across the PU and graphene nanoplatelet film-coated PBE membranes, indicating outstanding electric-heating features. Furthermore, the coating–compression cycles regulated the porosity of the prepared electric heating membrane.
Although such electric-heating-membrane-based wearable devices have been investigated, the insufficient flexibility and poor air permeability of conventional membranes limit their application. PU and Graphene Nanoplatelets for Wearable Devices Several carbon nanomaterial-based micro-nanofibrous membranes have been developed using various advanced methods, such as electrospinning, melt-blown processes, and solution blow spinning. These membranes are porous and facilitate the penetration of liquids and gases.
