Looking for flexible porous electrically conducting material

Click For Summary

Discussion Overview

The discussion revolves around finding a suitable flexible, porous, electrically conductive material to serve as a substrate for applying a polymer in a research project. Participants explore various material options, considering their properties and suitability for the intended application.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests carbonised or graphitic materials as potential options for the substrate.
  • Another participant proposes graphene, highlighting its electrical conductivity, smoothness, and flexibility, but notes its high cost.
  • Another suggestion includes ESD anti-static foam, which is not highly conductive but may be available in various conductivity ranges.
  • Microporous metals such as aluminium, copper, beryllium copper, and stainless steel are mentioned as possible materials.
  • A participant describes a method to create graphene from graphite oxide solution on a PET substrate, suggesting it could be a feasible approach.
  • Alum or copper metal foam is proposed for its high surface area, flexibility, and conductivity.
  • Thin carbon fibre cloth is recommended based on prior use for making electrodes in electrophoresis.

Areas of Agreement / Disagreement

Participants express a variety of suggestions without reaching a consensus on a single material. Multiple competing views and options remain under consideration.

Contextual Notes

Some suggestions may depend on specific definitions of flexibility, porosity, and conductivity, and the feasibility of proposed methods for creating materials like graphene is not fully explored.

For a research project I'm looking for a material to use as a robust substrate onto which I will apply a polymer. The ideal material would be flexible (or at least not brittle), porous to water and dissolved ions, relatively smooth and uniform (so that an even film of polymer can be cast onto its surface) and most importantly, electrically conductive.

I was thinking along the lines of some sort of carbonised or graphitic material, though I'm open to other ideas as well.

Any suggestions appreciated!

Graphene? (you said any suggestions:biggrin:) It conducts electricity, is smooth, flexible, don't remember the other properties right now (sorry).

How about just starting with ESD anti-static foam? It's not real conductive (100kOhm/square?), but it might be available in different conductivity ranges...

Yes, I've considered graphene and it sounds like amazing stuff with many of the properties I want. It is really expensive, though!
 
microporous aluminium/copper/beryllium copper/stainless steel .

You can make it, just get some graphite oxide solution, apply on PET substrate and reduce it with a flash from a flash-lamp, peel off layers of graphene from the PET. Its easy really! For the flash-lamp use the flash on cameras they are pretty much the same thing!
 
Alum or copper metal foam? High surface area, flexible if thin, highly conductive.
 
Try thin carbon fibre cloth. I used to use it for making electrodes for simple electrophoresis.
