The application area of a sound insulation material is highly dependent on the technology adopted for its processing. In this study, thermoplastic rubber (TPR, polypropylene/ethylene propylene diene monomer) composites were simply prepared via an extrusion method. Two microscale particles, CaCO₃ and hollow glass microspheres (HGW) chosen to not only enhance but also reinforced mechanical properties. Meanwhile, processing capability was confirmed. SEM images showed that uniformly dispersed in...
Cellulose/MWCNTs/TPU nanocomposite foams were successfully fabricated via a freeze-drying technique and ScCO 2 foaming. The microcellular structure of the composite showed potential application for polymer in wearable sensor devices.
Polymer foams are promising for sound absorption applications. In order to process an industrial product, a series of polystyrene (PS) composite were prepared by continuous extrusion foaming assisted supercritical CO₂. Because the cell size and density key determine coefficient at normal incidence, bio-resource lignin was employed first time control cellular structure on basis hetero-nucleation effect. The range PS/lignin corresponding content. As result, maximum incidence higher than 0.90....
The preparation of ultrastrong and super-tough polymeric materials for structural application remains a considerable challenge. To simultaneously enhance the strength toughness poly(lactic acid) (PLA), we successfully prepared PLA/poly(butylene-adipate-co-terephthalate) (PBAT) blends by biomimetically constructing mussel nacre-like hierarchically ordered superstructure through simple pressure-induced flow (PIF) processing technique. morphology, crystallization, mechanical properties were...
Notwithstanding that unprecedented progress has been achieved in strengthening and toughening PLA materials, it is still a challenge to find facile low-cost way improve poly(lactic acid) (PLA) strength, toughness, ductility while maintaining transparency biodegradability. Herein, strong, tough, transparent, highly heat-resistant materials with nacre-like lamellar structure were fabricated via simple, additive-free pressure-driven flow process. powders size under 500 μm heterogeneous...
In this work, a series of the thermoplastic elastomer (TPE) composites filled with micro CaCO 3 and hollow glass microspheres (HGM) via alloying process were investigated. The plastic phase TPE composite referred to polypropylene (PP) rubber was chosen by styrene butadiene (SBS). SEM observation conformed that inorganic particles mainly dispersed in continuous PP SBS remained an isolated structure. sound insulation property measured four-microphone impedance tube. Compared pure polymer...
Light weight, high sound insulation property polymers have vast potential application in aviation, auto industry and the military application. Pressure induced flow (PIF) process form multi-layer-oriented structure polymer matrix, supercritical CO2 foaming (ScCO2) introduce gas into matrix increase impedance mismatch between phase, both of them enhance property. In this paper, polypropylene (PP)/polyolefin elastomer (POE) blended composites prepared by PIF ScCO2 were measured using tube. The...
The pressure-induced-flow (PIF) processing can effectively prepare high-performance polymer materials. This paper studies the influence of on morphology, thermodynamic and mechanical properties polypropylene (PP)/polyamide 6 (PA6) blends, PP/polyolefin elastomer (POE) blends PP/thermoplastic urethane (TPU) blends. results show that significantly improve by regulating internal structure. Research shows increase strength toughness particularly in PP/TPU
This paper explored the injection foaming process of in situ fibrillation reinforced polypropylene composites. Using (PP) as continuous phase, polytetrafluoroethylene (PTFE) dispersed multi–wall carbon nanotubes (MWCNTs) conductive filler, and PP grafted with maleic anhydride (PP–g–MA) compatibilizer, a MWCNTs/PP–g–MA masterbatch was prepared by using solution blending method. Then, lightweight, PP/PTFE/MWCNTs composite foam means extruder granulation supercritical nitrogen (ScN2) foaming....
In this work,we dissolved the α-cellulose in pre-cooled sodium hydroxide (NaOH) and thiourea solution, dispersed multi-walled carbon nanotubes (MWCNTs) solution with help of cetyltrimethylammonium bromide (CTAB), then cross-linked for 48h to form a gel. The gel was placed distilled water displace hydroxide. After neutral, freeze-dried obtain cellulose/MWCNTs aerogel. We prepared cellulose aerogel 10 wt% MWCNTs, its density is 139.64 mg/cm3. Next, using as template, thermoplastic polyurethane...
In this work, a series of the thermoplastic polyester elastomer (TPEE) filled with micro CaCO3 and hollow glass microspheres (HGM) via alloying process. Meanwhile, processing-capability composites was confirmed. SEM images showed that uniformly dispersed in TPEE matrix ∼3 µm scale aggregates, while HGM slightly aggregated to ∼13 scale. The heterogeneous dispersion micro-scale fillers strongly affected sound transmission loss (STL) value composites. insulation property measured by four...
This paper proposed a method for preparing green renewable supercapacitor with lignin hydrogel as the solid electrolyte and polyaniline @ carbon cloth electrode. A series of LG-1.2, LG-1.6, LG-2.0 LG-2.4 hydrogels different cross-linking degrees were prepared using raw material polyethylene glycol diglycidyl ether crosslinking agent through simple reaction phenolic hydroxyl epoxy. Then, it is shown that appropriate degree can significantly improve compressibility water retention capacity...
