Problems solved by technology

However, the use of these binders can negatively affect the properties and performance of graphite felt
For example, the polymer binder reduces the surface area and the number of pores of graphite felt, leading to a drastic reduction of available active sites, thereby affecting the electrochemical, catalytic, and sensing properties of graphite felt.
In addition, the addition of low / non-conductive polymers affects the overall conductivity of graphite felt, which has a direct impact on the performance and efficiency of graphite felt in electrochemical and electronic applications

Abstract

The embodiments herein provide a facile four-step process for the preparation of binder-free graphene felts that are free standing and mechanically robust. The step of deagglomeration of graphene material leads to a uniform size distribution which when combined / integrated with an appropriate moulding technique allows an easy fine tuning of various attributes of graphene felts including electrical conductivity, porosity, surface area, surface morphology and surface functionalization depending on the desired application. Since graphene felts obtained from this process do not incorporate any binder, to achieve better electrical conductivity, electrochemical activity and catalytic and sensing properties compared to conventional graphene felts while not compromising with their mechanical properties.
