Abstract

Abstract : Graphitic carbon nitride (g-C3 N4 )/montmorillonite (Na-MMT) nanohybrids were fabricated and introduced into a sodium alginate with different levels. The introduction of 4.0 wt% nanohybrids led to the maximal improvement by ca. 149 °C in thermal stability. Abstract : Graphitic carbon nitride (g-C3 N4 )/montmorillonite (Na-MMT) nanohybrids were successfully fabricated by a facile mixing strategy and then introduced into a sodium alginate host to prepare nanocomposites with different loading levels using a casting technique. The introduction of 4.0 wt% nanohybrids led to the maximal improvement by ca. 149 °C in thermal stability. The improvement of the thermal stability was due to the reason that the mutual intercalation weakened the interlayered interaction of g-C3 N4 nanosheets or Na-MMT sheets and enhanced the physical barrier effect that retarded the permeation of heat and the escape of volatile products. This work may provide an approach for exploiting g-C3 N4 based materials.
