Design of superior conductive polymer composite with precisely controlling carbon nanotubes at the interface of a co-continuous polymer blend via a balance of π-π interactions and dipole-dipole interactions

In the current study, we propose an efficient thermodynamic method to precisely control multi-walled carbon nanotubes (MWCNTs) at the interface of a co-continuous PS/PMMA blend to design conductive polymer composites with ultralow percolation threshold. The achievement of the interfacial distribution of MWCNTs is attributed to the balance of π-π interactions between PS and MWCNT surfaces and dipole-dipole interactions between PMMA and carboxyl...
