Outline of Final Research Achievements

Epoxidized marine oils were synthesized using mild conditions for marine oils with polyunsaturated fatty acids. The newly marine biomass thermosetting resins were obtained by mixing and heating epoxidized marine oil and acid anhydride. The mechanical properties of the thermosetting resins were evaluated by tensile tests.The thermosetting resin prepared from EFO and methyl hexahydrophthalic anhydride (MHPA) exhibited a breaking strength of about 7.0 MPa. Furthermore, especially when the thermosetting resin was prepared with a small amount of bio-based bifunctional epoxy derivatives, its breaking strength was increased to 15 MPa.
A novel marine biomass composite material was prepared by EFO, MHPA and an impregnating chitin nonwoven fabric. The composite showed a breaking strength of 33 MPa and significantly improved mechanical properties. It is clear that chitin fibers play an important role as a reinforcing agent in the improvement of mechanical properties.
