Abstract

The disclosure provides compositions prepared by combining nanomaterials with a halide-containing polymer, thereby forming a combined polymer matrix having dispersed nanomaterials within the matrix. The nanomaterials may be carbon-based nanotubes, in some applications. A halide-containing monomer is combined with nanotubes, and then polymerized in some compositions. In other applications, a halide-containing polymer is solution processed with nanotubes to form useful compositions in the invention. Also disclosed are probes for near field detection of radiation.
