Enzymatic digestion of partially and fully regenerated cellulose model films from trimethylsilyl cellulose

► The enzymatic digestion of thin cellulose films regenerated from trimethylsilyl cellulose was studied. ► A quartz crystal microbalance (QCM) and capillary zone electrophoresis were applied. ► Surface analytical techniques were compared with the enzymatic digestion rates. ► The rate of regeneration correlated well with the digestibility. ► QCM and capillary zone electrophoresis are useful to determine the rate of regeneration.
