Preparation and characterization of polypropylene composites reinforced by functional ZnO/lignin hybrid materials

摘要: Abstract The aim of this study was to obtain polypropylene composites filled with a ZnO/lignin hybrid filler and examine their chemical mechanical properties. Inorganic-organic materials were obtained using an environmentally-friendly, low-cost method. use inorganic component mainly influenced the improvement thermal properties, in turn, lignin supported by its low price as well unique effectiveness production confirmed Fourier transform infrared spectroscopy and, indirectly, colorimetric analysis. In addition, stability porous structure analyses also carried out. Polymer containing 3 wt% each subjected wide angle X-ray diffraction tests differential scanning calorimetry studies define supermolecular Polarized light microscopy performed assess influence fillers on crystallization polypropylene. Tensile provided information regarding properties produced materials. presence influences nucleation activity it responsible for increased crystallinity degree composite samples. It established that introduction ZnO high amount into matrix resulted significant increase density formed nuclei.
