three-dimensional reduced graphene oxide (RGO)/polyaniline (PANI) composite has been prepared in a single step bYthe ultrasonic irradiation OFA suspension ofgraphite oxide and gels using a PANI method.Scanning electronic microscopy (SEM), Transmission electron microscope (TEM), X-ray diffraction (XRD), Fourier transform INfrared Spectra (FT-ir), X-ray photoelectron spectra (XPS), and electrochemical measurements were to performedThe morphology, structure, and supercapacitive performance of the composite.The result showed this composite maintained the basic morphology of RGO, and that's PANI was inlayed insideNetwork.An outstanding supercapacitive performance is obtained when the mass ratio ofgraphite oxide and PANI was 1:1.Furthermore, the capacities reached 758 and f*g _1 at 0.5 and 30a*g _1 , respectively.The retention rate is foundto is86%after1000 cyclesat received:october,2014;Revised:november:2014;Publishedon Web:november,2014. corresponding author.Email:tjpeng@swust.edu.cn";Tel: +86-816-2419276.

cellulose-based Functional composites exhibit the functional characteristics, such as light, electric, magnetic functionsand catalytic properties, which have been widely applied in pulping and papermaking, fine chemical, tissue engineering, BIOmedical and other fields.cellulose-based biomedical composites are typical cellulose materials, combining the advantages of both biomass and biomaTerials, which have potential applications in bone repair and replacement, tissue engineering, drug delivery, Gene CarrieR, protein adsorption, and other fields.In this review, we introduced three synthetic methods to composites including hydrothermal (Solvothermal) method, MicrowAve method and ultrasonic method, discussed the advantages and disadvantages of these three kinds of preparation,reviewed the progress of cellulose-based materials, and systematically summarized cellulose-based biomedical compOsites such as Cellulose/hydroxyapatite, Cellulose/calcium carbonate, and Cellulose/ag composites.Based on our experience, we pointed out the problems and future development of cellulose-based BiomedicalItes.It is expected to provide reference for the resourceful, functional, high-value, and recycling applications of biomass.In the future, it is desired to develop the manufacturing strategy for large-scale synthesis of cellulose-basedComposites, explore its synthetic mechanism, and reveal the intrinsic relationship the among, cellulose functionalIALs, methods and properties.It is so known that cellulose is difficult to dissolve in water or organic solvents under normal conditions because of tHe intra-and inter-molecular hydrogen bonds.Therefore, the development of suitable solvent for dissolving of cellulose is ofMproving their industrial applications. More recently, the cellulose Nanocrystal has received attentions to its due excellent.It is suggested this cellulose-based functional composites can be fabricated by using cellulose as matrix.Furthermore, rapid progresses are anticipated in the preparation of various-cellulose-based multifunctional composites including efficient antibacterial, flame retardant, waterproof, fireproof, adsorptive, anti-counterfeiting, RapidDetective and analytical functions.

TheFlame retardantcy polyethylene (PE) matrix composites were prepared by twin-screw extruder, WithHydromagnesite (HM) and Mg (OH)2As theflame retardants.The flame retardant properties and mechanism ofHM - Mg (OH)2/pe Flame retardant composites were investigated by limited oxygen index (LOI),Vertical buring Test (UL-94),Cone calorimetric Test (CCT) and universal tensile test.The thermal decomposition behavior of HM-MG (OH)2/pe flame RetardantComposites was studied by Thermogravimetric analysis (TGA).The resultsShow thisis, theflame retardant in appropriate proportionsofhmandMg (OH) 2decomposes inThe combustion tempera-ture range which leads to a better flame.In the premise of the same LOI and tensile strength, the cost of</b112> PE Composite with synergistic flame retardant decreases significantly with Mg (OH) 2asflame retardant alone.The ineffective even negative decomposition of HM reducesin the synergistic flame,/b13> and theInhibi Tory effect on the decomposition by thePE matrix with HM under high temperature is retained,At thesametime,a HeJunjie, CHENG Yu,ZHANG Xin, et al performance and decomposition behavior of HYDROMAGNESITE-MG (OH) 2synergistic polyethylene flame retardant composites[j].Acta materiae Compositae sinica,2017,(a):2674-2680 (in Chinese). Relatively stable scaly protective 1 ayer F orms i n the combustion region surface, in adition, the total lost mass of SYNEr Thegistic Flame Composite is higher.With those variety of factors, the flame retardancy effect of the synergistic flame Composite is higher.The HM-MG (OH2)/pe flame retardant Composites pass the UL-94 Vb13>-0rating with LOI valueof28%, and the tensile strength reaches 8 mpawhen mass ratio of HM to Mg (OH<b20>) 2is1:2 with 60wt% loading
