Ramanspectroscopic investigation of eco-friendly binder systems for carbon-bonded filters — •Simon Brehm1, Cameliu Himcinschi1, Benjamin Bock2, Christos Aneziris2, and Jens Kortus11Institute of Theoretical Physics, TU Bergakademie Freiberg, Germany — 2Institute of Ceramic, Glass and Construction Materials, TU Bergakademie Freiberg, Germany

Environmentally friendly binder systems for carbon-bonded filters based on lactose/tannin were investigated by Raman spectroscopy. In earlier samples, the carcinogenic material CarboresP was used as a binder [1], which is replaced by a lactose/tannin mixture in this work.

With Raman spectroscopy, the size of the sp2 carbon clusters using the intensity ratio of the D- and G-bands [2] and the -OH content can be qualitatively compared between different samples.

Temperature-dependent in-situ Raman measurements of the pure materials lactose and the tannin derivatives (tannic acid, gallic acid, ellagic acid) were performed.

Also two test series of the binder system were examined, one series was annealed to 1000C and one was untreated. Both series consist of six samples, whereby the initial CarboresP portion of 20% is gradually replaced by a lactose/tannin mixture.
