  • Gels containing the medicinal ingredients of licorice were formed by dissolving herbal medicinal plants into a biocompatible zwitterionic cellulose solvent and successive precipitation. The licorice gels gradually released glycyrrhizic acid, the main medicinal ingredient in licorice, within 3 h. Although the licorice gels were mechanically weak, the gel strength was improved just by the addition of cellulose during the preparation of the gels.

  • The effect of the viscosity of polycarbonate (PC) matrix on the thermal conductivity of PC/vapor-grown carbon fiber (VGCF) composite was investigated in terms of the rheological properties of PC/VGCF. Thermal conductivity of low viscosity PC increased with contents of VGCF in spite of adding the same amount of VGCF. From the result of the rheological properties which were originated in the network structure, we clarified that the dense network of VGCF could be formed in lower viscosity matrix.
