普通纸张模板纤维素碳化机理的研究与多孔木材陶瓷的制备

Study on Carbonization Mechanism of Common Paper Template Cellulose and Preparation of Porous Wooden Ceramic

以普通纸张和酚醛树脂为模板制备出新型多孔碳模板,深入研究纤维素碳化的机理。碳化过程的收缩率随树脂/纸张复合体中树脂含量的增大而减小;所得多孔碳的气孔率随树脂/纸张复合体中树脂含量的增大而减小,且随碳化温度的升高而减小;多孔碳的弯曲强度随树脂/纸张复合体中树脂含量的增大而增大,并随碳化温度的升高而增大。

The common paper and the phenolic resin were used as templates to produce new porous carbon templates, and the carbonization mechanism of cellulose was studied deeply. The shrinkage rate of carbonation decreased as the content of resin in resin/paper complex increased. The porosity of porous carbon decreased as the content of resin in resin/paper complex and the carbonization temperature increased. The bending strength increased as the con- tent of resin in resin/paper complex and the carbonization temperature increased.
