Cellulose nanofibers (CNFs) with an average diameter of 22 nm were prepared from sugar beet pulp (SBP) via environmentally-friendly method. Steam-explosion pretreated SBP was treated hydrogen peroxide (H2O2) bleaching, high-speed blending, and ultrasonic treatment. Thermogravimetric analysis showed that hemicellulose partially hydrolyzed in the steam-cooking stage, pectin removed explosion lignin by H2O2 bleaching. The removal non-cellulosic components confirmed Fourier-transform infrared...
A vane extruder is novel equipment for polymer processing. The materials were conveyed and plasticized by a group of plasticization units the suffered normal stress during An analytic model was developed to analyze conveying capacity melt in unit which can be positively. analysis shows that increased with rotate speed, eccentricity distance, width, inner-diameter stator. And leakage flow show width gaps but decreased apparent viscosity melt. experiment results linear variation production...
Insulating materials with high thermal conductivity have become the key to solving internal heat problem of electronic components. In this study, two fillers were prepared by in situ generation method. The uniform distribution silicon dioxide (SiO2) nanoparticles and silver (Ag) on surface graphene oxide (GO) carbide (SiC) was proved characterization methods such as micromorphology (TEM SEM) elemental analysis (XPS), respectively. above then added silicone rubber (SR) improve its...
Abstract Poly(3‐hydroxybutyrate‐4‐hydroxybutyrate) (P34HB) copolyester is a new type of biodegradable polymer material, but it cannot meet the market requirements because its poor thermal stability. In this work, P34HB with low degree cross‐linking was successfully prepared by incorporating small amount multiple epoxy chain extender, known as Joncryl ADR‐4380 (styrene‐methacrylic acid glycidyl ester copolymer), through reactive extrusion. The rheological properties, stability, behavior, and...
Abstract Polymer based materials with high conductivity and electric insulation are widely used in new electronic fields as thermal interface material (TIM). In this work, firstly we prepared the mixed fillers of silicon carbide (SiC) carbon nanotubes (CNT), then them to modify silicone rubber (SR) preparing composite SR. The experimental results TGA showed that had strong stability, mass loss was only 5% until about 370°C. Besides, significantly enhanced, which increased from 0.2 (pure SR)...
Polypropylene (PP) and polyethylene (PE) play central roles in our daily life. However, their immiscibility presents a major hurdle both industry academia when recycling them into alloys with favorable mechanical properties. Moreover, typical compatibilizer-enabled approaches are limited due to increased environmental concerns. Herein, inspired by traditional Chinese technique, we report facile, industry-scale methodology that produces PP/PE binary blend highly ordered honeycomb...
ABSTRACT A new laboratory‐scale mixing device called the “Vane Mixer” was designed, built, and tested. The vane mixer consists of three plasticizing conveying unit. In comparison with existing laboratory mixers, material flow in this is characterized by a high contribution from extensional flow. As has chamber very simple geometry, cleaning easy lost small. influences time rotor speed on dispersed phase size were discussed. Morphology data model immiscible polystyrene/high density...
Abstract Compounding montmorillonite (MMT) with polymorphic polyvinylidene fluoride (PVDF) by melt intercalation method can induce the crystal phase transformation of PVDF, which is great significance to obtain electroactive PVDF. In this research, PVDF/Organic‐Montmorillonite (OMMT) nanocomposites were prepared a novel vane mixer, was dominated elongational flow field in whole plasticizing. The dispersion OMMT, and resulting properties experimentally studied. results TEM WAXD evidenced that...
The preparation of ultra‐high‐molecular weight polyethylene (UHMWPE)/organoclay nanocomposites by continuous elongational flow technique was investigated in a novel eccentric rotor extruder (ERE). distribution and dispersion morphologies organo‐modified montmorillonite (OMMT) layers were revealed observed ash determination, wide angle X‐ray diffraction transmission electron microscopy. thermal thermal‐mechanical behaviors characterized differential scanning calorimeter, gravimetric analysis...
