Leila Bonnaud, CIRMAP and MateriaNova, Belgium: synthesis of benzoxazine resins from bio-sourced phenolic chemicals, such as eugenol (from clove oil or from lignin). The neat cured benzoxazine networks exhibit excellent thermal stability and high charring ability (>30% at 1000°C) combined with thermomechanical properties (Tg>200°C).
Addition of a small amount of carbon nano tubes (<<0.5wt%) results in big effects (significant shift of Tg to higher temperature –Tg>300°C-, electrical conductivity, shape of sample is retained after thermal degradation…)
