<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Pathogenic bacteria that cause harm to human health exist widely in daily life， and the chemical fungicides commonly used in sterilization will cause the resistance of bacteria and pollute the environment. Inorganic antibacterial agents prepared with metal/metal oxide nanoparticles （NPs） such as gold （Au）， silver （Ag）， copper （Cu） and zinc oxide （ZnO） have excellent physical antibacterial effects， and are not easy to cause bacterial resistance and environmental pollution problems， which have been widely concerned. However， metal/metal oxide NPs has some problems such as easy aggregation and fast release which limited its antibacterial effect. In this paper， the research progress of cellulose-based composite antimicrobial materials loaded with metal/metal oxide NPs were reviewed. The technical schemes for preparing NPs of Au， Ag， Cu and ZnO by physicochemical and biological methods， and the antibacterial mechanism of NPs were introduced. The preparation method of composite antibacterial material by loading metal/metal oxide NPs with cellulose and its derivatives not only solved the problem of fast release of NPs， but also contributed to improve the antimicrobial stability of NPs and reduced environmental pollution. Therefore， the cellulose-based composite antimicrobial materials loaded with metal/metal oxide NPs had broad application prospect in biomedicine， food packaging and other fields.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Lignin-based conductive hydrogels are prepared via cross-linking by lignin and its derivatives. As a by-product of pulp and paper industry， lignin come from a wide range of sources and their own functional groups are able to give hydrogels adjustable functional properties. Through different preparation methods， the added value of lignin can be further increased and the application range can be expanded. In this paper， based on the types， structural units and functional groups of lignin， the preparation methods of lignin-based conductive hydrogels were summarized according to different classification methods， and the research prospect of lignin-based hydrogel electrolytes used in supercapacitors with the good electrochemical performance at low temperatures was proposed.]]></description>

Introduction of hydrophilic groups to lignin structure can improve its solubility and surface activity， form lignin amphiphilic polymers， and further prepare lignin-based surfactants and stabilizers of Pickering emulsion. The paper reviewed the research progress of lignin-based amphiphilic polymers， and focused on the types， and influencing factors of lignin-based surfactants. The method， mechanism and application fields of amphiphilic polymers preparing from lignin protected by acetalization was discussed. In addition， the research status of Pickering emulsion stabilized by lignin-based emulsifier was summarized. Finally， the opportunities and challenges of converting lignin into value-added products were briefly described.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[This study prepared cellulose-based conductive filtration materials （hereinafter referred to as conductive filter materials） by compositing cellulose fibers and carbon nanotubes （CNT）， and connected the external static power supply to enhance the electrostatic adsorption efficiency of the conductive filter materials. The filtration performance for air particulate matter of the conductive filter material was controlled by changing the forming method， and regulating the basis weight of the conductive filter material and the CNT addition amount. The relationship between the applied electrostatic voltage and the filtration performance was further studied. The results showed that when the basis weight was 45 g/m<sup>2</sup> and the CNT addition amount was 50% （relative to basis weight of conductive filter material）， the conductive filter material CCP-50-45 showed the best overall filtration performance. After loading the conductive filter materials with high-voltage static electricity， the filtration efficiency enhancement of filter materials loaded electricity was linearly related to the CNT addition amount. The filtration efficiency of filter materials loaded electricity CCP-50-45-e for PM<sub>0.3</sub> was increased by 20.51 percentage points to 88.29% when the electrostatic voltage reached to 15 kV， and the pressure drop was kept unchanged with only 30 Pa.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Lignin， as a biomass resource second only to cellulose in nature， is of high research value because of its polyaromatic structure with ultraviolet absorption properties. However， industrial lignin has uneven molecular mass and structure due to different sources and extraction processes， and the product properties vary. In this study， the ethanol solution method was used to grade purified corn kernel industrial lignin （EL 0） to obtain three lignin grades： EL 100， EL 70， and ELR. Then the graded lignin was blended into commercial baby creams to prepare lignin-based sunscreens， respectively， and to evaluate their sun protection properties. The sunscreen properties of prepared lignin-based sunscreens were tested， the results showed that UV absorption capacity of lignin samples before and after fractionation was ELR &gt; EL 70 &gt; EL 0 &gt; EL 100 in descending order. When the mass fraction of lignin of lignin-based sunscreens was 10%， the sun protection factor （SPF） value of EL 0 sunscreen was only 12.55； the SPF value of ELR sunscreen reached 51.79， which enhanced the sunscreen performance while made the product darker in color. With an SPF value of 48.88， the EL 70 had a relatively lighter color for a wider range of applications. The results indicated that the graded treatment by ethanol solution method can effectively reduce the inhomogeneity of lignin structure and optimize the effect of lignin in sunscreen products.]]></description>
