Combination of a bio-based polyphosphonate and modified graphene oxide toward superior flame retardant polylactic acid
The superior flame retardant polylactic acid (PLA) composites were prepared using the bio-based polyphosphonate (BPPT) and polyethyleneimine modified graphene oxide (MGO) as flame retardant at very low loading amounts. Within 2.4 wt% BPPT and 0.6 wt% MGO in the polymer matrix, the as-prepared PLA composites can pass UL94 V0 grade and achieve a LOI value of 36.0. The cone tests and TG-FTIR results ...

Synthesis of phospholipidated β-cyclodextrin and its application for flame retardant polylactic acid with ammonium polyphosphate
In this study, phospholipidated b-cyclodextrin (PCD) was obtained by the condensation between b-cyclodextrin and phenyl phosphonic acid dichloride, which was characterized by Fourier transform infrared (FTIR) spectra, 1H-NMR, and thermogravimetric analysis (TGA). The thermal stability and flame retardancy of the poly(lactic acid) (PLA) blends [PLA–ammonium polyphosphate (APP)–PCD] were measured ...

Construction of multilayer coatings for flame retardancy of ramie fabric using layer-by-layer assembly
Complex multilayer coatings composed of a-zirconium phosphate (ZrP), polyethylenimine (PEI), and ammonium polyphosphate (APP) were constructed via layer-by-layer assembly method for flame retardant ramie fabric. Bicomponent PEI/ZrP layers served as insulating barrier coating, and bicomponent PEI/APP layers served as intumescent coating. The flame retardancy of the coated ramie fabric was strongl...

Smoke suppression effect of graphene nanoplatelets fabricated by friedel-crafts reaction in brominated flame retarded polystyrene
Graphene nanoplatelets (GNPs) were introduced into polystyrene (PS)/brominated polystyrene (BPS) blend to overcome the large amounts of smoke generated from the brominated flame retardant during combustion. A Lewis acid catalyst (AlCl3) was introduced to initiate Friedel-Crafts reaction to produce the macrocarbocations interacted with graphene sheets by electrostatic attraction, leading to a...

Flame Retardancy and Thermal Stability of Polypropylene Composite Containing Ammonium Sulfamate Intercalated Kaolinite
Ammonium sulfamate (AS) intercalated kaolinite (K) was successfully prepared through a three-step method, and then, it was introduced in association with intumescent flame retardants (IFR) into polypropylene (PP). The structure of intercalated kaolinite (AS-K) was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and X-ray p...

Preparation of a Novel Intumescent Flame Retardant Based on Supramolecular Interactions and Its Application in Polyamide 11
The flammability and melt dripping of the widely used bio-based polyamide 11 (PA 11) have attracted much attention in the last decade, and they are still a big challenge for the fire science society. In this work, a novel single macromolecular intumescent flame retardant (AM-APP) CRI that contains an acid source and a gas source was prepared by supramolecular reactions between melamine and p-amino...
