摘要：

Here we present a general concept of wet surface esterification of cellulose using acyl imidazoles, which enables direct acetylation of never-dried cellulose fibres in aqueous conditions. We hope that due its simplicity and resource-efficiency, this method will have a widespread influence on currently used (nano)cellulose modification protocols.
