Gels Serving as Carriers for Functional Fillers and Facilitating Novel Composite Paper Production

Abstract

Functional fillers can facilitate the development of novel composite paper products for specific end uses. But using functional components as fillers by direct addition to the fiber suspension may fall short of the desired goals. The functional filler may fail to be efficiently retained. Gels can serve as carriers of functional paper fillers by coupling with them during in-situ synthesis and the gelation process. This strategy is favorable for the effective utilization of functional paper fillers, without hampering the intrinsic properties of paper. Additional merits of this strategy include versatility and compatibility with existing paper-making processes.
