Abstract
<p>Functional hybrid materials based on magnesium lignosulfonate and silica were obtained and characterized. Magnesium lignosulfonate is a common waste product of the wood pulp industry, while silica is a well-known inorganic material with exceptional physicochemical properties. In this study, silicas with a spherical particle shape were synthesized using a sol-gel method and alternatively in a nonpolar medium. Silica was found to improve the thermal and electrokinetic properties of the final products. The resulting lignosulfonate/silica hybrid materials were analyzed with the use of advanced techniques and measuring methods: scanning electron microscopy, a laser diffraction method enabling particle size measurements, Fourier transform infrared spectroscopy, elemental analysis, thermogravimetry, electrophoretic light scattering, zeta potential measurements, low-temperature nitrogen sorption, and colorimetric analysis. The results enabled the hybrid materials to be characterized from the point of view of potential applications in various branches of industry (for example as polymer fillers, electroactive blends and biosorbents). We additionally indicate new methods for the utilization of waste products, a category to which lignosulfonate certainly belongs.</p>
Highlights
The combining of organic and inorganic materials to obtain novel and functional hybrids is a topic of growing importance
We report here the results of an experiment in which magnesium lignosulfonate, a renewable biopolymer formed in the process of paper production, was interconnected with silica, an inorganic material with defined physicochemical and structural properties
It can be seen from the table that for the silica obtained via the sol-gel method, 10% of particles by volume have a diameter less than 5.7 μm, 50% less than 12.1 μm, and 90% up to 22.6 μm
Summary
The combining of organic and inorganic materials to obtain novel and functional hybrids is a topic of growing importance Many such materials are synthesized with the use of natural macromolecules such as cellulose [1–3], lignin [4–6] or lignosulfonate [7–8]. Lignosulfonates have been applied as an additive to drilling fluid in order to improve the effectiveness of oil extraction Due to their adsorptive and surface active properties these materials cause the agglomeration of dust particles, which precipitate and can be collected. We report here the results of an experiment in which magnesium lignosulfonate, a renewable biopolymer formed in the process of paper production, was interconnected with silica, an inorganic material with defined physicochemical and structural properties. The resulting magnesium lignosulfonate/silica hybrid materials were analyzed to determine key physicochemical, dispersive-morphological, electrochemical and other parameters
