Composites consisting of polylactide (PLA) and poly(ε-caprolactone) (PCL) filled with acid-oxidized multiwalled carbon nanotubes (A-MWCNTs) were prepared through melt compounding. Phase morphologies PLA/PCL/A-MWCNT composites different contents A-MWCNTs PCL compositions mainly observed by scanning electron microscope. The results show that are selectively dispersed in the phase, regardingless phase domain sizes. For fixed PLA/PCL ratio 95/5, sizes PLA matrix decrease even though a small...
Biodegradable polylactide (PLA) composites added with acid oxidized multiwalled carbon nanotubes (A-MWCNTs) of two different aspect ratios (length to diameter) were prepared by coagulation. The and surface structures A-MWCNTs characterized TGA, Raman, SEM measurements. percolation thresholds for gelation in the PLA large small are 2.5 4.0 wt %, respectively, which determined a rheological method, turn, result confirms ratio differences types composites. Isothermal crystallization kinetics...
A series of asymmetric biodegradable poly(l-lactide) (PLLA)/poly(d-lactide) (PDLA) blends with low PDLA compositions was prepared using a solution blending method. The formation stereocomplex (SC) crystallites in PLLA/PDLA evidenced by differential scanning calorimetry (DSC), as indicated the melting point SC being about 50 °C higher than that PLLA homocrystallites. Isothermal crystallization kinetics under shear conditions at specific high temperature 160 for investigated polarized optical...
Composite thermoplastic elastomers (CTPEs) of magnetic copolymer-grafted nanoparticles (magnetite, Fe3O4) were synthesized and characterized to generate CTPEs, which combined the property Fe3O4 elasticity grafted amorphous polymer matrix. served as stiff, multiple physical cross-linking points homogeneously dispersed in poly(n-butyl acrylate-co-methyl methacrylate) rubbery matrix via activators regenerated by electron transfer for atom radical polymerization method (ARGET ATRP). The...
A very bright white light was obtained by combining the advantages of red, green and blue quantum dots with photonic crystal structures.
Infrared invisibility has continued to develop in recent decades, triggered by novel physics, advanced fabrication technology and raw materials. However, the quick response of infrared stealth during transmedia (water–air/water–land) movement, which is important practical scenarios, not been investigated. Here, we employ random thermal effect interaction between laser matter construct a bionic flexible thin-film superhydrophobic cloak. The average emissivity cloak 0.224 over 8–14 μ <italic...
Integrated power dividers (PDs) are essential in terahertz (THz) communication and radar systems, but miniaturization often leads to performance degradation due fabrication inaccuracies sharp bends. Topological photonics offers a solution these issues, yet creating THz with arbitrary splitting ratios remains challenging. We present design methodology for on-chip topological customizable using valley-locked photonic crystals. These crystals feature tri-layered structure two distinct valley...
Cellulose-graft-poly[poly(ethylene glycol) methyl ether acrylate] (Cell-g-PPEGA) and poly[poly(ethylene (PPEGA) comb-like copolymers were synthesized by electron transfer atom radical polymerization (ARGET ATRP). PPEGA/PLA Cell-g-PPEGA/PLA pairs are both immiscible as indicated slightly decreasing glass transition temperatures of PLA in the blends measured differential scanning calorimetry (DSC) phase separation morphologies observed a contrast optical microscope (PCOM). double-layer films...
Abstract The thermal degradation behaviors of poly-p-phenylene-benzimidazole-terephthalamide (PBIA), poly-m-phenylene isophthalamide (PMIA) and poly-p-phenylene terephthalamide (PPTA) fibers are investigated by thermogravimetric analysis (TGA) coupled with Fourier transform infrared spectroscopy (TGA-FTIR). results demonstrate that PBIA fiber exhibits better thermal- thermo-oxidative stability than the other two polymers. shows highest onset temperature, both in nitrogen air. TGA-FTIR...
Abstract Different generation hyperbranched polyurethanes (HBPUs) were synthesized through the A 2 +B’B strategy. The molecular structures and viscosity characterized by nuclear magnetic resonance (NMR) spectroscopy gel permeation chromatography (GPC). NMR results confirmed formation of branched units between segments contained in HBPU structure. GPC with a four-capillary bridge design differential viscometer Ubbelohde showed different viscosity. For HBPUs, first increased to higher values...
Abstract Isotactic polypropylene/ultrahigh-molecular-weight polyethylene blends (iPP/UHMWPE) and iPP/carbon nanotubes composites (iPP/CNTs) were prepared by a coagulation method followed compression molding. The percolation thresholds for melts of iPP/UHMWPE iPP/CNTs determined rheometer, beyond 5.0 wt% close to 4.0 wt%, respectively. creep creep-recovery behavior systematically investigated rheological measurements. results indicated that UHMWPE CNTs played similar roles in the material’s...
The urban traffic network of Jinzhou city was split by the Beijing-Shenyang railway. intersects south and north railways at only four bridge openings, congestion subsequently occurs in these areas. Railway crossing district is analyzed. In order to find operating characteristics north-south most crowed opening during peak hour, geometric openings are volumes investigated addition, hour found. saturation degree then calculated. study provides basic information for guidance.
Abstract Crystallization processes of polylactide (PLA)/acid oxidized multiwalled carbon nanotube (A-MWCNT) composites were detected by dynamic rheological measurements. The influences pre-shear, crystallization temperature, concentration and aspect ratio A-MWCNT, on the kinetics PLA, investigated. addition small amounts can more or less accelerate PLA matrix. Composites with smaller A-MWCNT (A-MWCNT–S) show faster rates than those larger (A-MWCNT–L), due to heterogeneous nucleation sites...
