A facile and green method to hydrophobize films of cellulose nanofibrils and silica by laccase-mediated coupling of nonpolar colloidal particles
(2014-10-01)
Article
Accés restringit per política de l'editorialHydrophobic particles based on dodecyl 3,4,5-trihydroxybenzoate (LG) were coupled onto the surface of cellulose nanofibrils (CNFs) and silica by treatment with a multicomponent colloidal system (MCS) derived from the ... -

Accés restringit per decisió de l'autorLa materia prima utilizada es eucalipto (Eucalyptus globulus). Se utiliza las astillas de eucalipto y por medio de procesos como la Autohidrólisis y la cocción Kraft seguidamente de procesos de blanqueo como el blanqueo ... -
Functionalization of cellulosic model substrates via laccase-mediated coupling of non-polar particles
(2014)
Text en actes de congrés
Accés restringit per política de l'editorialIn the present work we investigate the physicochemical interactions between silica and nanofibrillar cellulose (CNF) with a multi component system (MCS) obtained from an enzymatic reaction of a laccase enzyme and a short-chain ... -
Increasing yield of nanocrystalline cellulose preparation process by a cellulase pretreatment
(2015-06-09)
Article
Accés obertIn this work the introduction of a cellulase treatment prior to NCC isolation was assessed. NCC was produced using sulfuric acid at two different concentrations (62 and 64% wt.). The effect of pore size for filtration step ...
