Binder applications of cellulose nanofibrils: new developments

A key path towards the commercialization of cellulose nanomaterials is to target large-volume applications in commodity products where a successful market introduction could potentially mobilize orchestrated efforts to revitalize the forest products industry. At the Laboratory of Renewable Nanomaterials we have introduced the concept of using cellulose nanofibrils (CNF) as binder in conventional wood based compressed panels. Binder applications take advantage of impressive hydrogen bonding capacity of CNF and have many other uses. In this presentation, we will present our findings in wet-formed particleboard bonded with cellulose nanofibrils (CNF). In an effort to lower the production cost, we have also shown that lingo-cellulose nanofibrils can be produced directly from wood and can be used as binder in the formulation of traditional fiberboard panels. Thermomechanical pulp (TMP) produced using atmospheric refining was ground to isolate lignocellulose nanofibrils (LCNF). The effect of using LCNF as adhesive replacement in fiberboard was assessed. Future outlooks, potential issue and methods to implement large volume applications of CNF are discussed.
