Chemically Modified Lignin – a Potential Resource Material for Composites with Better Stability
نویسنده
چکیده
In this study, Kraft softwood lignin was treated with acetic and propionic anhydride to produce esterified lignin. Reactions were performed at 85 ̊C. The product was characterized using IR, DSC and different parameters required to index the ease of processoperation. The chemically modified as well as esterified lignin was then blended with biorenewable polymer such as polylactide (PLA) and extruded into composite films. The films were then subjected to routine analysis like FTIR and TGA. In addition to that mechanical properties were also verified by standard tensile testing protocols. Preliminary results gave a positive indication to go for further studies. This will confirm the results and establish the range of properties achievable.

Sustainable Green Hybrids of Polyolefins and Lignin Yield Major Improvements in Mechanical Properties When Prepared via Solid-State Shear Pulverization
Lignin, a byproduct of paper and pulp industries, is a sustainable, inexpensive biomaterial with potential as composite filler. Past research on polyolefin/lignin composites made by melt processing has led to modest increases in Young’s modulus and drastic reductions in tensile strength and elongation at break relative to neat polymer. Here, green hybrids of low density polyethylene (LDPE) and ...
متن کاملPreparation and Characterization of Novel PVC/Silica–Lignin Composites
An advanced SiO2–lignin hybrid material was obtained and tested as a novel poly(vinyl chloride) (PVC) filler. The processing of compounds of poly(vinyl chloride) in the form of a dry blend with silica–lignin hybrid material and, separately, with the two components from which that material was prepared, was performed in a Brabender mixing chamber. An analysis was made of processing (mass melt fl...
متن کاملDimensional Stability, Uv Resistance, and Static Mechanical Properties of Scots Pine Chemically Modified with Alkylene Epoxides
Unprotected wood exposed outdoors suffers from photodegradation due to absorption of UV light by lignin and dimensional changes because of moisture absorption or desorption by free hydroxyl groups in wood constituents. Chemical modification of cell wall polymers is one of the effective methods of inducing dimensional stability and UV resistance in wood. In this work, etherification of Scots pin...

Chemical modification of hardwood sawdust from ash-tree species was carried out with a solution of maleic anhydride in acetone. Wood polymers, lignin, and cellulose were isolated from the wood sawdust and modified by the same method. Samples were characterized by Fourier transform infrared spectroscopy (FTIR), providing evidence that maleic anhydride esterifies the free hydroxyl groups of the w...

Functional lignin-SiO₂ hybrid fillers were prepared for potential application in binders for phenolic resins, and their chemical structure was characterized. The properties of these fillers and of composites obtained from them with phenolic resin were compared with those of systems with lignin or silica alone. The chemical structure of the materials was investigated by Fourier transform infrare...
