Poly(butyl methacrylate) (PBMA)/Fullerene (C70) nanocomposites were successfully prepared by solvent removal method and characterized different techniques. Structural characterization showed an interaction between PBMA C70 nanofiller. Morphological features that was homogeneously distributed in the matrix. Optical analysis confirmed formation of with wavelength shift PBMA/C70 compared to pure PBMA. Photoluminescence spectra emission bands shifted from blue red presence new region. The data obtained thermal Tg increased about 10 °C maximum decomposition temperatures improved 65–70 °C, confirming stability. thermogravimetric analyses performed at heating rates analyzed Kissinger-Akahira-Sunose (KAS) Flynn-Wall-Ozawa (FWO) equations calculate activation energy values. According regression coefficient values, experimental results good agreement FWO (R2PBMA=0.937 R2PBMA/C70 (5 wt%)=0.953). fullerene doped nanocomposite calculated as 48 kJ/mol 104 kJ/mol, respectively Ea value higher than
