Synthesis and characterization of Oligo-PIs/Alumina composites |
| 초록 |
Polyimide oligomers (oligo-PIs) were successfully prepared from thermal imidization of ɑ-BPDA and TPE-R as a monomers, 4-PEPA acted as a reactive end-capper and DMAc as a solvent. The formulation of the composites were manufactured by mixing the oligo-PI and alumina sol with the alumina sol contents. Oligo-PIs/alumina composites could be synthesized via the thermal crosslinking reaction of the end-capped phenylehynyl group at 370℃. The mechanical and the thermal properties of the composites were studied using impact strength, flexural strength and thermogravimetric analysis (TGA). The morphology of the oligo-PIs/Alumina composites were investigated by scanning electron microscope (SEM). The thermal properties of oligo-PIs/alumina composites were enhanced gradually as the amounts of alumina sol increased. And impact strength of the composites was remarkably improved. It is expected that alumina sol in the composites be dispersed uniformly by the morphologies. |
