Stabilization of poly(vinyl chloride) using iodine vapor for preparing carbon aerogels

It is well known that the atmosphere of the stabilization significantly influences the carbonization behavior of the organic compounds and the resulting carbon structure. For the conversion of coal tar pitches into carbons, the use of iodine vapor as the stabilization atmosphere is exceedingly effective to increase the carbon yield. This paper uses iodine vapor as the stabilization atmosphere for preparing the PVC-based carbon aerogels, and investigates the differences of the carbonization behavior between the aerogels stabilized in air and iodine vapor.
