Abstract

We report the use of ionic liquids as novel impregnates to enhance the carbon yield of cellulose based carbon fibres. It was found that ILs which contain a phosphate anion improved the carbon yield the most, with a 50% increase in carbon yield reported. Additionally the use of the ionic liquid impregnate lowered the depolymerization temperature by 70 °C, which reflects significant potential saving in the energy costs of carbonization.
