Abstract
Enzymatic degradation of model cellulose films pre-treated with antimicrobial agent, 3-(trimethoxysilyl)-propyldimethyloctadecyl ammonium chloride (TMPAC) was investigated. AFM topographical imaging was used to assess the surface morphology, roughness, and thickness of the dried and hydrated model cellulose film. The kinetics of the model cellulose film in the hydrated state, the adsorption of TMPAC onto the film followed by desorption given by an enzyme extracted from Trichoderma Viride were studied by in situ null ellipsometry. The results show that the adsorption of TMPAC onto model cellulose film slows down the rate of degradation, as confirmed by a slower decrease in the film mass and by different behaviour of the thickness of the...
