Paper Title:
Preparation of a New Porous Material: Enzymatic Hydrolysis Lignin Woodceramics
  Abstract

A new porous material, lignin woodceramics (WCS), was successfully prepared with enzymatic hydrolysis (EH) lignin as its raw material, through modifying, mixing with lignin, drying, moldings, and sintering. Its yields, hardness and microstructure were analyzed. Because of the phenolic structure of EH lignin, which is similar to phenol- formaldehyde (PF) resin, the yields of mass, diameter, and thickness was almost the same with those of the samples made of PF resin treated material. The hardness of the product with 20% (w/w) the modified lignin in dosage was 30% higher than that of control, and it was also better than that of the sample made of PF resin to original EH lignin of 5: 95. SEM analysis showed that the plant tissue was largely strengthened by PF resin through swelling, filling and covering, but modified lignin worked not as efficiently as PF resin to strengthen WCS. However, this new material, EH lignin WCS, does not rely on phenol and will have a promising future.
