INTRODUCING CATIONIC GROUPS TO STARCH/FATTY ACID COMPLEX MODIFIED MINERAL FILLER PARTICLES BY PARTIAL SUBSTITUTION OF UNMODIFIED STARCH WITH CATIONIC STARCH FOR IMPROVING FILLER-FIBER INTERACTION IN CELLULOSIC NETWORKS
Interaction of unmodified starch with certain guest molecules(e.g.,fatty acids)as a basis for the formation of starch inclusion complex based hybrids is an effective process for enhancing the interaction of mineral filler particles with cellulosic fibers.In this mini-study,the concept of substituting unmodified starch with a minor amount of cationic starch in filler engineering was proposed.It was hypothesized that filler-fiber interaction would be enhanced by cationic-anionic attraction.Encouragingly,the effectiveness of this concept was demonstrated to be very pronounced.For instance,at a cationic starch percentage of 3%(related to the weight of total starch),filler/starch retention and filler bondability with cellulosic fibers were significantly improved,leading to further mitigated negative impact of filler addition on tensile strength.Basically,this easily scalable concept may shed light on greener,more efficient use of filler technologies on the basis of starch inclusion complex formation,opening up new possibilities for commercial applications.
