Entropy squeezing for a two-level atom in motion interacting with a quantized field

para-Aramid fiber modified by melamine polyphosphate and its flame retardancy on thermoplastic polyurethane elastomer

“…The LOI test is widely used to evaluate the thermal stability properties of polymer materials, particularly for screening ame retardant formulations of polymers. 2 The LOI results obtained from the TPU composites are presented in Fig. 2.…”

“…TPU is widely used in many elds due to its excellent high tension, high tensile strength, toughness, resistance to aging properties, etc. 1,2 However, similar to many other thermoplastics, due to its high ammability and the large amount of hightemperature toxic smoke released during its combustion, TPU has caused great pollution and harm to the environment. [3][4][5] As a result, its applications in many elds are greatly limited.…”

Improving the flame retardancy of waterborne polyurethanes based on the synergistic effect of P–N flame retardants and a Schiff base

“…[1][2][3][4] However, the high ammability of polyurethane materials limit their application in everyday use. [5][6][7] To endow WPU with ame retardant properties, various halogen-free ame retardants have been introduced, 8-11 among them, phosphorus containing ame retardants have attracted much attention. Typically, the traditional phosphorus-containing ame retardants scavenge the active radicals OHc or Hc in the gas phase, and facilitate dehydration and carbonization in the condensed phase.…”

Synthesis of a novel char‐forming agent (PEIC): Improvement in flame retardancy, thermal stability, and smoke suppression for intumescent flame‐retardant polypropylene composites

“…As one of the most extensively used polymers, polypropylene (PP) plays important roles in wide range of areas, such as architecture, furniture, and car, due to its good properties in plasticity, corrosion resistance, electric insulation, and so on . However, the characteristics of inflammability seriously deteriorate its safety when subjected to high temperature or open flame, largely restraining the use of PP . Whereupon, it is necessary to make PP flame‐retarded.…”
