Acrylonitrile-butadiene-styrene resin (ABS)/graphene nanocomposites were prepared through a facile coagulation method. Because the chemical reduction of graphene oxide was in situ conducted presence ABS at dispersion stage, aggregation nanosheets avoided. It shown by transmission electron microscopy that selectively located and homogeneously dispersed styrene-acrylonitrile (SAN) phase. The electrical conductivity linear viscoelastic behavior systematically studied. With increasing filler...
Abstract Low-dimensional materials exhibit unique quantum confinement effects and morphologies as a result of their nanoscale size in one or more dimensions, making them distinctive physical properties compared to bulk counterparts. Among all low-dimensional materials, due atomic level thickness, two-dimensional possess extremely large shape anisotropy consequently are speculated have optically anisotropic absorption. In this work, we demonstrate an optoelectronic device based on the...
The synergistic effect of 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) immobilized silica (SiO 2 ‐DOPO) nanoparticles with an intumescent flame retardant (IFR) on the retardancy polypropylene (PP) was investigated by UL 94 vertical tests and limiting oxygen index (LOI) measurements. It found that PP/IFR composites (25 wt%) achieved UL94 V0 grade LOI increased to 32.1 incorporation 1.0 wt% SiO ‐DOPO nanoparticles. Based thermogravimetric analysis, scanning electronic microscopy...
Electrochromic effect refers to the electrically tunable coloration of a matter. Emerging see-through color-tunable applications pose synergetic demand on electrochromic device, concurrently having ultralow field driving, operation in transmissive mode, and high-purity interference colors sci-fi perception. However, such an device remains elusive. Herein, we invent electro-interference-color based two-dimensional titania liquid crystals (2D TiO 2 LCs), demonstrating record-high...
A new flame retardant polycarbonate/magnesium oxide (PC/MgO) nanocomposite, with high retardancy was developed by melt compounding. The effect of MgO to the retardancy, thermal property, and degradation kinetics were investigated. Limited oxygen index (LOI) test revealed that a little amount (2 wt %) led significant enhancement (LOI = 36.8) in retardancy. Thermogravimetric analysis results demonstrated onset temperature maximum rate decreased both air N2 atmosphere. Apparent activation...
Abstract A novel microencapsulated ammonium polyphosphate (MAPP) with shell of crosslinked β‐cyclodextrin (HDI‐CD) was prepared. The HDI‐CD had a fibrous structure and covered good completeness on the APP core, solid chemical bonding found between core shell. microcapsules were more hydrophobic than pristine APP. When compounded within polypropylene (PP), MAPP exhibited compatibility dispersibility. combustion testing results showed that all‐in‐one intumescent flame retardant efficient...
ABSTRACT Encapsulation of expandable graphite (EG) particles by organic or inorganic shells has been proved to efficiently enhance the expandability EG, and thus improve flame‐retardant efficiency EG. In this study, magnesium hydroxide (MH) nanosheets were utilized fabricate core–shell EG@MH through a heterocoagulation method. It was observed that after encapsulation MH nanosheets, edges char residue EG layer sealed combustion, which contributed enhancement expandability. The expansion...
Abstract Magnesium hydroxide (MH) nanoparticles have been considered as an excellent nonhalogen flame‐retardant. However, the drawbacks of easy aggregation and relatively low flame retardancy limit their applications in polymer materials. In this research, MH were successfully grafted by 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) through bridge vinyl silane coupling agents (WD70). The (MH‐WD70‐DOPO) characterized Fourier transform infrared spectra, 31 P nuclear magnetic...
The objective of this study is to improve the performances ceramic UV stabilizers in polymer nanocomposites. Silica coated ZnO nanoparticles were prepared and melt blended into polypropylene (PP) matrix order introduce an inert silica shell between chains as isolation layer protect against photodegradation. resistance nanocomposites was evaluated by accelerated aging test. results indicated that photocatalytic activity particles suppressed via encapsulating with silica. could effectively stability PP
ABSTRACT Rutile‐type titanium dioxide (TiO 2 ) nanorods were prepared, superficially modified and tested for the protection of polypropylene (PP) from UVB UVC irradiations. The silica coating blocked active sites on following calcination further reduced amount surface hydroxyl groups thus, made TiO more efficient against photodegradation. Compared with spherical nanoparticles, calcined silica‐coated demonstrated good photostabilization efficiency due to excellent shielding effect improved...

Abstract The ammonium intercalated montmorillonite (A-MMT), especially acid treated (H-S-A-MMT), which experienced silane grafting treatment, exhibited highly exfoliation state in poly(ethylene terephthalate) (PET) matrix. It can be explained that the shear stress was transferred effectively from molten polymer to clay layers during melting processing due enhanced polymer-clay interaction by grafted silane, leading slippage and peeling of sheets. Furthermore, equilibrium point reduction...
