| Summary: | 碩士 === 國立中興大學 === 化學工程學系所 === 100 === We have successfully prepared maleimide-functionalized CNTs (BMI-CNT) via Diels-Alder reaction of MWCNTs with 1,1''-(methylenedi-p-phenylene)bismaleimide (DDM-BMI) . Among the solvent we have tried, DMAc is the best solvents for the modification, as supported by thermal gravitational analysis of organic content. IR spectrum confirms the C=O, and C-N bonds of BMI-CNT. The modification was also supported by intensity change of ID/IG in Raman spectrum, and the well dispersion of BMI-CNT in DMSO, DMF, and ethanol. The maleimide linkage act as a bonding cite with cyanate ester.
Phenolic OH-containing benzoxazine (o-OHBz), which cannot be easily prepared by traditional procedures, have successfully been prepared from the condensation of bis(4-amino-3-phenol) and 2-hydroxybenzaldehyde, reducing the resulting imine linkage by NaBH4, and ring closure condensation. The phenolic OHs can provide a reaction cite with epoxy and 1,1''-(methylenedi-p-phenylene)bismaleimide (DDM-BMI). The structure-property relationships between p-OHBz/epoxy, F-a/epoxy, p-OHBz/DDM-BMI, F-a/DDM-BMI copolymers were discussed.
