The invention relates to methods and compositions for improving the fluid, electrical or strength properties of a polymer by binding an effector moiety to the polymer via a protein. The invention particularly relates to improving the properties of paper by binding thereto a moiety capable of conferring a property such as improved wet strength, dry strength or sizing, via a protein such as a cellulase capable of binding to cellulose in the paper.
Ces procédés et compositions permettent d'améliorer les propriétés fluides, électriques ou de résistance d'un polymère par liaison à celui-ci d'une fraction effectrice par l'intermédiaire d'une protéine. On améliore ainsi en particulier les propriétés du papier en y liant une fraction pouvant lui conférer une propriété telle qu'une résistance accrue à l'état humide ou sec ou un encollage amélioré, grâce à une protéine telle qu'une cellulase pouvant se lier à la cellulose de ce papier.
