Abstract 2‐Carboxyethyl(phenyl phosphinic) acid has been proved to modify flame retardant properties of poly(ethylene terephthalate) (PET) through copolymerization; however, there is no industrial technological breakthroughs in polyester yarns which requires high strength and modulus, because it related the coordinated control molecular weight retardancy. In this work, influence solid‐state polymerization reaction kinetics parameters on retardancy retention have investigated, based prepared...

Interaction between N-methylmorpholine N-oxide (NMMO), H2O, and the titanium dioxide (TiO2) surface was studied by spectral tests molecular dynamics simulations as theoretical foundation for development of functional lyocell. The structure, movement, arrangement NMMO water molecules, well interaction energies them, were characterized. results show that both molecules can interact with TiO2 surface, molecule is stronger, which makes near different from bulk solution. With increase...

Ceramic coatings based on sol-gel method have increasingly gained much attention in recent times. In order to ascertain important experimental factors (variables) influencing surface properties, such as adhesion, pencil hardness and advancing contact angle (non-stick) of sol coatings, a 2 6-1 -factorial screening design with six variables, precursor mole ratio, low energy polymer concentration, silane coupling agent (SCA) silica nanoparticles concentration (SNP’s),curing temperature three...

Abstract To confirm the effect of surface property carbon black (CB) on lyocell process and chemical stability solvent N‐methylmorpholine N‐oxide (NMMO), molecular dynamics simulation ultraviolet tests were performed to investigate interaction between aqueous NMMO solution CB surfaces with different polar groups. The hydrophobic O 2 atom unmodified increased an increase in concentration. improved dispersion solution, but this was not sufficient prevent aggregation particles. Modifying a...
