This article focused on the synthesis of poly( p ‐phenylene benzobisoxazole)/carboxylic multiwalled carbon nanotubes (PBO/MWNT‐COOH) composites through in situ polymerization. The effect of MWNT‐COOH on thermal stability and photophysical properties was investigated thoroughly. Especially an in‐depth study was carried out on the detailed process of energy transfer. Ultraviolet‐visible‐near infrared and fluorescence spectroscopy of composites revealed that MWNT interacted with PBO through strong covalent bonds, which was a significant photoinduced charge‐transfer interaction between the two components. Therefore, compared with PBO, both the thermal stability and PL quantum efficiency of PBO/MWNT‐COOH composites were improved. POLYM. COMPOS., 2012. © 2012 Society of Plastics Engineers
