Abstract

We report on a series of novel experimental results based on deoxyribonucleic acid (DNA)-biopolymer host/conductive nanoparticle guest composites and polymethylmethacrylate (PMMA)-amorphous polymer host/conductive nanoparticle guest composites. Surprisingly, the EMI shielding effectiveness measured ~40% higher using the DNA-based biopolymer host than those of the PMMA host. The comparison between the material processing, thin film fabrication and electromagnetic interference shielding effectiveness, using both types of host materials are presented.
