Title:ResponseSurfaceOptimizationofAcetylationModificationofNanocellulose
Abstract:
Nanocellulose,apromisingnanomaterialderivedfromcellulose,hasgainedconsiderableattentionduetoitsexcellentmechanicalproperties,highaspectratio,andrenewablenature.However,itshydrophilicnaturerestrictsitsapplicationsinvariousfields.Oneapproachtoovercomethislimitationistheacetylationmodificationofnanocellulose,whichimpartshydrophobicityandimprovedcompatibilityinpolymermatrices.Inthisstudy,weaimedtooptimizetheacetylationmodificationofnanocelluloseusingaresponsesurfacemethodology(RSM)toinvestigatetheeffectsofvariousprocessparametersonacetylationefficiencyandtofindtheoptimalconditions.
