<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Polyurethane （PU） is one of the most widely used polymer materials， in which area the synthesizing technology of non-isocyanate polyurethane （NIPU） from biomass resources is receiving increasing attention. Lignin is a natural and renewable aromatic polymer with abundant reserves in nature. Functionalized lignin can be a substitute for the unsustainable petroleum-based raw material in developing high value-added NIPU products. This paper reviewed methods and strategies for synthesizing NIPU using lignin as a raw material， summarized the research progress regarding synthesizing lignin-based NIPU using lignin and its functionalized derivatives， as well as prospected the potential applications of lignin-based NIPU in foam materials， wood adhesives， elastomers， coatings and other related fields.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In this study， formic acid lignin and its nanoparticles were isolated and prepared from corn stover， poplar and pine wood with different liquid ratios （1∶10， 1∶9， 1∶8， and 1∶7） using formic acid of pulping process. The difference of phenolic hydroxyl contents in different formic acid lignin was explored. The results showed that the formic acid lignin obtained from the three raw materials had the basic characteristic structure of lignin， and the phenolic hydroxyl contents of lignin at the liquid ratio of 1∶9 was 2.69， 2.82， and 3.09 mmol/g， respectively. The results of water contact angle experiments showed that the lignin compression tablets of three raw materials had strong hydrophilicity. Formic acid lignin nanoparticles were used for the preparation of formic acid lignin nanoparticles/starch composite films， and the contact angle of composite films was significantly increased， and the hydrophobic properties were influenced by the type of raw materials and liquid ratios. The contact angle of composite films after four months aging was further enhanced， and corn stover， poplar and pine formic acid lignin/starch composite films had the highest water contact angles of 127.2°， 125.1° and 123.5°， respectively. The study results played a positive role in promoting hydrophobic performance of lignin， and developing applications of hydrophobic films.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Lignin with polar groups such as phenolic hydroxyl， alcoholic hydroxyl， and carboxyl groups can be used to improve the efficiency of plant nutrient utilization in soil due to its high complexing properties. It also can improve soil agglomerate structure， and increase soil enzyme activity. Besides， lignin can adsorb and remove pollutants in soil through ion exchange and complexation interactions， and induce microbial degradation of organic pollutants， thus playing a role in remediation of contaminated soil. The principle of lignin in soil improvement and remediation were summarized in this paper， and the application effect of lignin as soil conditioner， sand fixer and pollutant adsorbent were described. Finally， the progress of research and application of lignin in this field was summarized， and corresponding suggestions were proposed for its future development.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[This paper reviewed the research progress of lignin modified materials in the adsorption and removal of dyes from water. Firstly， the structure of lignin was analyzed， and the adsorption performance of modified lignin was analyzed with a focus on different types of dyes （methylene blue， Congo red， malachite green）.By discussing the structure-effect relationship between adsorption properties and lignin modification methods （phenolic modification， sulfonation treatment and graft copolymerization）， this paper revealed the advantages of modified lignin in improving the adsorption capacity， increasing the selectivity， and facilitating the regeneration of the adsorbent， and offered a prospect for the future direction of the development of lignin-based adsorbent materials.]]></description>
