The increasingly sophisticated counterfeiting technology has led to a significant increase in the demand for more advanced anticounterfeiting materials, and multimode luminescent materials are promising candidate anticounterfeiting. In this research, dual-mode nanocomposite, SiQDs-Ln, was designed prepared by grafting lanthanide ions (Eu3+/Tb3+) onto surface of trimellitic anhydride-functionalized blue-emitting silicon quantum dots (SiQDs). This preparation strategy can effectively prevent...
Designing hydrogels with adequate strength, remarkable swelling resistance, low friction coefficient, excellent biocompatibility, and osseointegration potential is essential for replacing articular cartilage. However, it remains challenging to integrate all these properties into one material. In this work, a Janus hydrogel was prepared from polyvinyl alcohol, chitosan, sodium hyaluronate, followed by one-sided dipping in situ precipitation mineralization form layer of hybridized...
A new multifunctional benzoxazine monomer Azo-COOH-Py BZ includes an azobenzene unit, a carboxylic acid group, and pyrene moiety.
In order to overcome low crystallization rate of PET, HPN-68L was selected replace the special nucleate agent PET improve for its carboxylate anion structure which usually showed high induced nucleation ability PET.
The intermolecular hydrogen-bonding formed between PBT and TDP can efficiently mediate the crystallization behavior of PBT.
In this study, a graphene oxide (GO)-based thermoresponsive smart catalytic material with phase-transition temperature of approximately 37 °C was developed by growing poly( N-isopropylacrylamide) (PNIPAM) on GO sheets (i.e., GO-PNIPAM). The composite characterized Fourier transform infrared spectroscopy, N2 adsorption, thermogravimetric analysis, organic elemental differential scanning calorimetry, and X-ray photoelectron spectroscopy. GO-PNIPAM-supported Ru catalysts Ru/GO-PNIPAM) were then...
The crystallization behavior of n-C19H40/SiO2 nanosphere composites was investigated by a combination differential scanning calorimetry (DSC) and temperature-dependent X-ray diffraction (XRD). Three kinds confined alkanes with different solid−solid phase transition supercoolings surface (or interface) freezing monolayer n-C19H40 at the bulk liquid/SiO2 interface were found in high SiO2 loading. induces chain packing forming 2D close-packed arrangement without long-range positional ordering...
Abstract Developing hydrogels with excellent mechanical performances and multiple functions is challenging. Herein, polyvinyl alcohol (PVA) grape seed extracted polymer (GSP) were used to achieve this goal. The hydrogel was firstly cross‐linked by crystalline regions of PVA upon freezing–thawing cycles, it further immersed in ammonium sulfate (AS) solution induce the hydrophilic hydrophobic transition GSP. relationship between microstructures properties obtained PVA–GSP revealed. results...
In the current work, polypropylene composites filled with a [email protected] filler antibacterial and antistatic properties was firstly synthesized. The fabricated nanocomposites were characterized using SEM, TEM, XRD, FTIR XPS techniques. With addition of protected], composite materials are greatly improved by synergistic effect AgNPs T-ZnOw. When content is 10 wt%, activity material against Gram negative (Escherichia coli) positive (Staphylococcus aureus) bacterial 100%. And surface...
Poly(ethylene terephthalate) (PET) and aryl amide derivative (TMB-5) blends were prepared by melt blending. It was found that TMB-5 shows a significant nucleation effect on PET especially the non-isothermal efficiency reached up to 80.7% at very low content of 0.6 wt% TMB-5. The effects crystallization behavior mechanical properties systematically investigated. DSC results show temperature apparently increased nearly 20 °C with addition during cooling process. A remarkable acceleration in...
Abstract Due to the brittle performance of polyamide 6,12 (PA6,12) in high impact environment, we report a facile, efficient, and scalable method toughen PA6,12 by establishing intermolecular hydrogen bonding (H‐bonding) interaction with 3‐pentadecylphenol (PDP). Interestingly, H‐bonding obviously hindered PA crystallization, which was evidenced decrease crystalline temperature from 186.8 175.8°C prolong crystallization half‐time 0.27 0.37 min, when amount PDP increased 30 wt%. Consequently,...
Abstract The high crystallinity and fast crystallization rate of polypropylene (PP) often result in severe warpage final parts prepared by means material extrusion additive manufacturing (MEAM). In this work, the effect bed temperature ( T b ) nozzle n on dimensional accuracy mechanical property MEAM‐printed PP copolymer was investigated. It is found that raising could significantly reduce regulating behavior PP. Specially, amount γ‐crystal grows obviously while total remains unchanged, as...
Abstract A polyvinyl alcohol (PVA)‐agarose (agar) composite hydrogel (M‐PVA‐agar‐60) was developed by simple three cycles of freeze‐thawing, followed successively soaking in ammonium sulfate aqueous solution to induce phase separation and dialyzing against deionized water remove residual salts.
