Abstract Biofibers, natural lignocellulosics, have an outstanding potential as a reinforcement in thermoplastics. This study deals with the preparation of lignocellulosic composites by reactive extrusion processing which good interfacial adhesion is generated combination fiber modification and matrix methods. PP was modified reacting maleic anhydride subsequently bonded to surface component, in‐situ. The it silane simple quick aqueous reaction system, similar that employed for glass fibers....
Two-dimensional atomically thick materials such as graphene and layered molybdenum disulfide (MoS2) have been studied potential energy storage because of their high specific surface area, redox activity, mechanical flexibility. However, the structure restacking poor electrical conductivity, these are unable to attain full potential. Composite electrodes made a mixture MoS2 shown partially resolve issues in past, although performance is still limited by inadequate mixing at nanoscale. Herein,...
There are increasing requirements worldwide for advanced separation materials with applications in environmental protection processes. Various mesoporous polymeric have been developed and they considered as potential candidates. It is still challenging, however, to develop economically viable durable from low-cost, mass-produced materials. Here we report the fabrication of a nanofibrous network structure common polymers, based on microphase technique frozen polymer solutions. The resulting...
Lithium-ion capacitors (LICs) represent a new type of energy-storage devices, which have combined merits high energy density Li-ion battery and power supercapacitor. Nevertheless, one significant challenge for LICs is the imbalanced kinetics between fast capacitive cathode relatively slow intercalation anode that limit performance. Here, asymmetric LIC devices were developed based on nitrogen-doped, carbonized zeolitic imidazolate framework (ZIF-8) three-dimensional, nano-network-structured,...

To prepare sample, 4 wt% aqueous PAM solution is mixed organic cross-linkers hydroquinone (HQ) hexamethylenetetramine (HMT) in 1:1 weight ratio potassium chloride (KCl) solution. A specific amount above added to sand, well mixed, subsequently cured 150 °C 8 h. The prepared...
Three-dimensionally cross-linked polymer nanocomposite networks coated nano sand light-weight proppants (LWPs) were successfully prepared via ball-milling the macro and subsequently modifying resultant with sequential coating. The modified had good sphericity roundness. Thermal analyses showed that samples can withstand up to 411 ℃. Moreover, proppant samples’ specific gravity (S.G.) was 1.02–1.10 g/cm3 excellent water dispersibility. Therefore, particles act as potential candidates...

Hydrophobic mesoporous polymer nanofibre networks were converted to hydrophilic ones by a mild sulfonation reaction. The resultant polystyrene with large free surface area effectively captured water-soluble dye molecules and allowed aromatic compounds rapidly permeate into the internal binding sites.
