Abstract
P
ackaging has increasingly become a dominant factor in the global market competitiveness: this implies also obtaining new raw materials with improved packaging properties. Material from locally cultivated date palm was used as a packaging additive, showing potential in improving strength and barrier properties. In particular, date palm sheath (DPS) cellulose nano-crystals (CNCs) were prepared by ammonium persulfate (APS) treatment of unbleached, bleached and mercerized fibers. The influence of the reaction parameters on the CNCs were studied. Besides APS extraction, CNCs were also isoltaed from DPS fibers using mineral acids ( sulfuric & phosphoric). The effect of cellulose polymorphs on CNC isolation were studied too. The characteristics of DPS-CNCs prepared by APS treatment were compared with those of CNCs obtained by the two acid hydrolysis treatments. The CNCs degree of substitution and surface charge density were determined by conductometric titration and zeta potential measurements, respectively.
