Synthesis and Structural Characteristics of Organic Aerogels with Different Content of Lignin

Article Preview

Abstract:

Lignin can be used as a cheap raw material to prepare organic and carbon aerogels based upon the sol-gel reactions. Different concent lignin organic aerogels have been prepared by sol–gel polymerization of formaldehyde with resorcinol, following by the process of RF-gel production and subsequent freeze drying. The resulting materials were characterized by FT-IR analysis, nitrogen adsorption, transmission electron microscopy and Scanning electron micrographs. The structural properties organic aerogel depend on the amount of lignin added to the sol-gel system. and the LRF aerogels obtained in the experimental have an open cell structure with continuous porosity and homogeneous spherical particles.
