摘要
A composite was prepared in which octa-methylmethacrylate polyhedral oligomeric silsesquioxane (POSS) is polymerized as the matrix and carbon nanotube (CNT)-adsorbed 1-allyl-3-methylimidazolium hexafluorophosphate ionic liquid (IL) is used as the filler, which exhibited a high dielectric constant and low dielectric loss owing to a POSS coating layer formed in situ on the CNT surface between the vinyl groups of the IL and POSS.
