The novel application of chitosan: Effects of cross-linked chitosan on the fire performance of thermoplastic polyurethane.
In this paper, a novel flame retardant (ACS) was prepared by crosslinking chitosan with bis-(4-formylphenyl)-phenyl-phosphonate (ABPO). ACS in association with ammonium polyphosphate (APP) and organic modified montmorillonite (OMMT) were used to prepare flame retardant thermoplastic polyurethane (TPU) composite through melt blending. For the TPU sample containing 10% flame retardants, the limiting...

Enhancing mechanical performance of epoxy thermosets: Via designing a block copolymer to self-organize into "core-shell" nanostructure
ABSTACT: A rigid-flexible amphiphilic pentablock copolymer, polystyrene-block-poly(3-caprolactone)-blockpolydimethylsiloxane-block-poly(3-caprolactone)-block-polystyrene (PS-PCL-PDMS-PCL-PS, SLDLS), was designed. SLDLS block copolymers will self-organize into “core–shell” nanostructures in epoxy thermosets, with rigid PS as the “shell” and flexible PDMS as the “core”. Due to the incorpora...

Study on the Performance of Polycarboxylate-based Superplasticizers Synthesized by Reversible Addition–fragmentation Chain Transfer (RAFT) Polymerization
ABSTRACT: A series of block type polycarboxylate-based superplasticizers (PCs) with different molecular architectures were synthesized with macromonomer butenyl alkylene polyoxyethylene-polyoxypropylene ether (BAPP) and acrylic acid (AA) by reversible additionefragmentation chain transfer (RAFT) polymerization. Fourier-Transformed Infrared (FTIR) Spectroscopy and dynamic light scattering (DLS) w...

Effect of nano-montmorillonite as cell opener on cell morphology and resilient performance of slow-resilience flexible polyurethane foams
Abstract: In this paper, polypropylene glycol Y-1900, unmodified nano-montmorillonite (MMT) and organically modified nano-montmorillonite (OMMT) serving as cell openers are introduced into slow-resilience flexible polyurethane foams (FPUFs), aiming at investigating the effects of
them on cell morphology and the relationships between cell structure, nano-montmorillonite types and resilient per...

Polymeric Microcapsules with Sustainable Core and Hierarchical Shell toward Superhydrophobicity and Sunlight-Induced Self-Healing Performance
Photopolymerization is considered as one of most promising candidates for microcapsules-embedded self-healing system due to its significant advantages, e.g., fast, energy efficient and commonly economical. However, many microencapsulated photopolymerizable healing agents are usually expensive, unsustainable, or even environmentally hazardous. Herein, a polymeric microcapsule with hierarchical shel...

Impact of moderative ligand hydrolysis on morphology evolution and the morphologydependent breathing effect performance of MIL-53(Al)
In this paper, a facile route is reported for the synthesis of MIL-53(Al) particles with different sizes and morphologies via the addition of various ratios of an esterified ligand to realize the deferred release of the ligand. Detailed proof indicates that the hydrolysis and deferred release of the ligand play a crucial role in modulating the morphology and size of the obtained MIL-53 nanoparticl...

Synthesis of Mesoporous gamma-Al2O3 with Spongy Structure: In-Situ Conversion of Metal-Organic Frameworks and Improved Performance as Catalyst Support in Hydrodesulfurization
Over the past decades, extensive efforts have been devoted to modulating the textural properties, morphology and microstructure of γ-Al2O3, since the physiochemical properties of γ-Al2O3 have close correlations with the performance of hydrotreating catalysts. In this work, a spongy mesoporous γ-alumina (γ-Al2O3) was synthesized using Al-based metal-organic...

High-performance poly (ethylene oxide)/molybdenum disulfide nanocomposite films: reinforcement of properties based on the gradient interface effect
Herein, the molybdenum disulfide (MoS2) was simultaneously exfoliated and non-covalently functionalized by ultrasonication in a Plutonic aqueous solution and then was used, to prepare the poly(ethylene oxide) (PEO) based nanocomposite films. The homogeneous dispersion of MoS2 and strong nanosheets/matrix interfacial adhesion were confirmed by representative electron microscopes. The considerable '...

Metal-coordination crosslinked N-polyindoles as recyclable high-performance thermosets and nondestructive detection for their tensile strength and glass transition temperature
Metal coordination crosslinking between stiff N-polyindole chains was constructed, and the crosslinked films exhibited high tensile strength, high heat resistance and excellent polar solvent resistance. The noncovalent crosslinking can be further removed via external pyrophosphate, which endows the crosslinked polymer with a recyclable behavior. The tensile strength and glass transition temperat...
