【摘要】 |
Nanocarbon–poly(methyl methacrylate) sols were prepared by pulsed laser ablation at the interface of target submerged in flowing liquid (PLA-IT/SFL) method, and the corresponding composite films were prepared by solution-casting. Spectra results indicated that there existed interactions between nanocarbon and the polymethyl meth acrylate (PMMA) matrix, which was consistent with the decrease in glass transition temperature of the composites with increase of carbon content. TEM images revealed that a carbon encapsulated core/shell structure was formed in the composites, which could ensure good dispersion of carbon nanoparticles within the PMMA matrix. The decomposition of the composites was less influenced by the introduction of nanocarbon particles. |
