Design and characterization of functional TiO-lignin fillers used in rotational molded polyethylene containers.

In this study, new TiO-lignin hybrid systems were synthesized and characterized by various methods, including non-invasive backscattering (NIBS), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), elemental analysis (EA) and zeta potential analysis (ZP). The weak hydrogen bonds between the components, as shown on FTIR spectra, proved the production of class I hybrid systems. TiO-lignin systems were found to display good thermal stability and relatively good homogeneity.
