Novel phosphorus-containing dicyclopentadiene-modified phenolic resins for flame-retardancy applications

Thermal properties and combustion behaviors of flame retarded epoxy acrylate with a chitosan based flame retardant containing phosphorus and acrylate structure

“…The peak at 1300 cm −1 was ascribed to the stretching vibration for P O structure, where represented the graphitelike polynuclear aromatic structure [43,44]. This change indicated that the phosphate group deviated from the aliphatic structure and formed the P O structure around 400 • C. The peak at 1100 cm −1 assigning to the stretching vibration of P O bond moved to lower wavenumber.…”

Functionalization of carbon nanotubes by furfuryl alcohol moieties for preparation of novolac phenolic resin composites with high carbon yield values

“…Carbon yield value of the phenolic resins is commonly increased by structural modifiers, additives, and a combination of these methods. Phenolic resins are structurally modified with boron, molybdenum, and phosphorous compounds [4][5][6][7][8]. In addition, graphene and carbon nanotube (CNT) are two main carbon additives for phenolic resins [9][10][11][12][13][14].…”

Thermal properties and flame retardancy of an ether-type UV-cured polyurethane coating

“…Meanwhile, the changes of several peaks are examined with increasing temperature. The peak for the P=O bond (1263 cm -1 ) is shifted to higher wave number at 1294 cm -1 , which is assigned to the P=O stretching vibration of P-O-Φ structure, where Φ represents the graphite-like polynuclear aromatic structure [16,27]. As the temperature elevates to 305°C, the bands of 773 and 692 cm -1 are shifted to lower wave numbers at 752 and 675 cm -1 , attributed to out-of-plane bending vibrations of aromatic C-H for P-O-Φ complex structures [16,28].…”
