Surface studies of novel hydrophobic active carbons

▶ We have synthesized a microporous carbon with a hydrophobic surface which gives enhanced breakthrough times (+40%) for filter-beds used for the separation of certain organic vapours under high humidity (80% RH) conditions. ▶ These materials also show improved (reduced) ageing under high humidity storage compared to standard carbons. ▶ They also give us an insight into the fundamental mechanism of water adsorption by active carbons and, by disrupting this process, allowing us to test current theories and ideas.
