Scholarcy highlights

  • Starting from renewable Cardanol, a novel inherently fire-retardant UV curable bio-based prepolymer with phosphazene core and six Cardanol arms are prepared in this report
  • UV-curable mixture consisting of AEHCPP and different diluents were formulated and their photopolymerization dynamics were investigated on Photo-calorimetry
  • Differential Scanning Calorimetry and Dynamic Mechanical Analysis results show that glass transition temperatures of all cured films are above room temperature, the 5% weight loss temperature in nitrogen is higher than 266 °C
  • The fire-retardant properties are estimated by TGA and all calculated Limiting Oxygen Index values are over 24, implying the excellent fire-resistance of cured films
