Research topics from publications: A bio-based benzoxazine surfactant from amino acids; Benzoxazine-epoxy thermosets with smectic phase structures for high thermal conductive materials. Representative work: A bio-based benzoxazine surfactant is synthesized using amino acids as an amine source, and may have potential use in cosmetics and cleaning products To further increase the intrinsic thermal conductivity (TC) of polybenzoxazine, a series of benzoxazine-epoxy thermosets (s-PBEI) were obtained through the sequential curing of a smectic phase epoxy monomer (s-EP) and a bifunctional benzoxazine monomer (BZ) in the presence of imidazole. The results show that s-PBEI exhibits a smectic mesophase. The formation mechanism of the smectic phase is reaction-induced phase separation caused by the preferential curing of s-EP. Owing to the increment of the liquid crystalline structure content, the TC of s-PBEI increases with increasing s-EP content. The TC of s-PBEI55 containing equal weight of BZ and s-EP reaches 0.30 W m−1 K−1, which is higher than
