The novel incorporation of lignin-based systems for the preparation of antimicrobial cement composites

Popis výsledku v původním jazyce

Lignin is an organic material with interesting application potential in the design of new materials. In this paper, the effect of TiO2–SiO2 (1:1 wt./wt.) and lignin mixed by a solvent-free mechanical process on cementitious materials was investigated for the first time. The designed hybrid materials were extensively characterized by Fourier ransform infrared spectroscopy (FTIR), thermal analysis (TGA/DTG) and scanning electron microscopy (SEM). In addition, the electrokinetic potential as a function of pH and particle size distributions as well as porous structure were also characterized. In the next step, the effect of the TiO2–SiO2/lignin hybrid admixture on the workability, microstructure, mechanical properties, porosity, hydration process and antimicrobial properties of the cement composites was evaluated. It was observed that appropriately designed hybrid systems based on lignin contribute to better workability, higher microstructure density, better strength parameters and lower porosity of cement composites. In addition, the TiO2–SiO2/lignin hybrid systems had significant potential due to their high microbial purity, suggesting their effectiveness in minimizing microbial accumulation on surfaces. In conclusion, the use of TiO2–SiO2/lignin admixtures is a promising area for the valorization of lignin waste flows in the design of cement composites.
