Paper Title:
Lignin-Hydroxyapatite/Tricalcium Phosphate Biocomposites: SEM/EDX and FTIR Characterization
  Abstract

In the present work, a novel biocomposite has been developed based on lignin (Lig) and HA/b-TCP bioceramic materials. The Lig/HA and Lig/b-TCP systems were investigated by Scanning Electron Microscopy coupled to EDX microprobe (SEM/EDX). Lignin is a lignosulfonate natural polymer with complex random coupling and the exact chemical structure is yet unknown. FTIR spectroscopy is an important tool for lignin characterization based on several major vibration bands associated with generally found chemical groups. Consequently, FTIR spectroscopy was used to evaluate the chemical functionalities and major components present in the material. SEM photomicrographs of biocomposites Lig/HA and Lig/b-TCP have shown uniform dispersion of the natural polymer binder in the bioceramic matrix. Also, chemical composition obtained by EDX spectra have indicated lignin evenly distributed in the HA and b-TCP compounds. Novel biocomposites based on lignin/HA and lignin/b-TCP were developed with porosity ranging from 50 to 100 µm. These results have confirmed the high potential application of lignin as a non-toxic natural polymer binder to be used as 3D scaffold template for biomedical applications.
