Journal ArticleDOI
The effect of chitosan on the flammability and thermal stability of polylactic acid/ammonium polyphosphate biocomposites.
TL;DR: X-ray diffraction and differential scanning calorimetry results demonstrated that the presence of APP and CS could promote the crystallization of PLA, and the interaction between CS and APP could provide synergistic effects in improving the flame retardancy of PLA biocomposites.
Journal ArticleDOI
Preparation and characterization of chitosan derivatives and their application as flame retardants in thermoplastic polyurethane
TL;DR: Thermogravimetric analysis and char morphology observation demonstrated that SCS/APP could promote the char formation to form more intact intumescent char structure and it was proposed that the synergism between CS derivatives and APP might be responsible for the improvement of flame retardancy.
Journal ArticleDOI
Intercalation of phosphotungstic acid into layered double hydroxides by reconstruction method and its application in intumescent flame retardant poly (lactic acid) composites
TL;DR: In this article, a phosphotungstic acid intercalated MgAl-LDH was prepared by reconstruction method, and it was then introduced into poly (lactic acid) (PLA) resin in association with intumescent flame retardant (IFR) by melt blending to prepare a flame-retardant biodegradable PLA composite.
Journal ArticleDOI

TL;DR: It is suggested that AM-APP produces an intumescent char structure and releases inert gases, whereas TiO2 may consolidate the char layers, leading to the improvement in the fire resistance of PA 11.
Journal ArticleDOI

TL;DR: In this paper, a single macromolecular intumescent flame retardant (DT-M) was prepared by self-assembly of diethylenetriamine penta-(methylenephosphonic) acid with melamine, and modified layered double hydroxides (LDH) were also prepared by intercalating phytic acid into LDHs.
