<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Composite materials prepared by plasticized modifying plant fibers are environmentally friendly and sustainable， which can reduce the reliance on synthetic plastics. Used eucalyptus fibers as raw materials in this study， the deep eutectic solvent （DES） was used for pretreatment to improve the accessibility of eucalyptus fibers while retaining the cellulose framework structure and rigidity. Then， a hydrophobic modified polyurethane prepolymer （BDO-PU） was grafted from 1，4-butanediol （BDO）， hmethylene diisocyanate （HDI）， and polyethylene glycol （PEG）， and the fiber-based plasticized modified films with plastic processability were prepared. The results showed that when the mass ratio of eucalyptus fibers pre-treated with DES to BDU-PU was 3∶1， the tensile strength and the Young’s modulus of the BDO-PU plasticized modified film could reach 27 and 792 MPa， respectively. The wet tensile strength and wet Young’s modulus after 2 h immersion treatment still remained at 22 and 483 MPa， respectively. Under this condition， the surface hydrophobicity of BDO-PU plasticized modified film was enhanced， with a water contact angle of 118° and an equilibrium water absorption rate of 63%. The material exhibited good thermal stability and excellent thermoplastic processing performance.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Cellulose films were prepared through the regeneration combined with hot-pressing method using dissolving pulp as the raw material and 1-allyl-3-methylimidazolium chloride/dimethyl sulfoxide （AMIMCI/DMSO） as solvents， and the effects of the hot-pressing process on the strength properties of the cellulose films were primarily investigated. The results indicated that hot-pressing enhanced the inter-molecular bonding of cellulose in the films， generated stronger hydrogen bonds and established a denser hydrogen bond network， thereby significantly improved the strength properties of the cellulose films. Hot-pressing for 0.5 h under the conditions of temperature of 80 ℃ and pressure of 1 MPa， the prepared cellulose film achieved a tensile strength of up to 210 MPa with toughness of 60.8 MJ/m³. Moreover， hot-pressing treatment further improved the optical transmittance and surface smoothness of cellulose films， achieving a transmittance of 92% and a surface roughness as low as 3 nm.]]></description>

<link><![CDATA[http://zgzzxb.ijournals.cn/zzxben/ch/reader/view_abstract.aspx?file_no=202503018&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Lignin exhibits unique structures with benzene rings and side chains， and is rich in functional groups， such as phenolic hydroxyl， carboxyl， and carbonyl groups. Thus， lignin can form hydrogen bonds and π-π stacking， as well as participate in various chemical reactions of oxidation， esterification， and sulfonation， thereby enhancing its reactivity and conversion efficiency. Based on the distinct structral characteristics， lignin presents significant application potential in the field of functional materials， especially in the development and application of functional coatings. This paper introduced the classification and characteristics of lignin based on differences in separation methods， and focused on the application research progress in some fields of functional coatings such as UV resistance， hydrophobicity， anticorrosion， antibacterial and barrier properties. It also looked forward to the development trend and high-value application of lignin functional coatings.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Increasing the deposition and adhesion rate of pesticide droplets on leaves is an important means to improve the utilization efficiency of pesticides and meet the challenges of pesticide application. In this study， sulfate lignin was used as raw material to modify the structure of lignin by tannic acid. Tannic acid modified lignin nanoparticles （TA-LNPs） were obtained by anti-solvent method and used to stabilize the Pickering emulsion loaded with metolachlor. A simple and efficient agricultural chemical delivery system was constructed. The deposition performance of lignin-based Pickering emulsions （TA-PEs） on the leaf surface and the sustained release behavior and UV degradation behavior of metolachlor in the emulsion were investigated. The contact angle between TA-PEs and the leaf surface was 37.92°， showing good leaf wetting ability. After coating with TA-PEs， the deposition of metolachlor on the leaf surface could reach 81.53%. At the same time， TA-PEs also showed UV protection effect on metolachlor. After 24 h of UV irradiation， the retention rate of metolachlor was 77.46%. The leaf wettability of TA-PEs， the leaf deposition performance and the UV light stability of herbicides were better than those of commercial sodium dodecyl benzene sulfonate stabilized metolachlor emulsion.]]></description>
