| Abstract | Carbon nanofibers (CNFs) were modified via plasma polymerization using methyl methacrylate (MMA) as monomer and used as reinforcements for polymethyl methacrylate (PMMA). Conditions of the MMA plasma process in a specially designed reactor and plasma-polymerized methyl methacrylate (PPMMA) films were studied. The study involved varying the process time at a constant plasma power of 100 W and a constant MMA flow rate (0.15 cm3 per min). Nanocomposites of PPMMA-coated CNFs and PMMA were prepared with 0.5, 1.0, 2.0, 4.0 and 8.0 %wt of treated CNFs. The effect of the MMA plasma on the CNFs was analyzed. Dispersion of the modified CNFs was evaluated in several solvents. The results confirmed a change in hydrophobicity of the treated CNFs. The inclusion of treated CNFs exhibited substantial impact on the properties of the PMMA/CNF nanocomposites. The thermal and mechanical properties of the PMMA/CNF composites were examined. It was found that the thermal stability increased by about 8% and the Young´s modulus significantly enhanced by as much as 178% when compared to PMMA with no CNFs. |
