1. A dispersion comprising:
- about 10 wt % to about 95 wt % of at least one organic solvent based on the total weight of the dispersion;
about 5 wt % to about 80 wt % of nanoparticles based on the total weight of the dispersion, wherein the nanoparticles are infrared absorptive, conductive or both infrared absorptive and conductive; and
about 0.5 wt % to about 50 wt % of at least one polycaprolactone-polyamine copolymer based on the total weight of the dispersion,wherein the dispersion comprises agglomerates of the nanoparticles and a majority of the agglomerates have an average diameter that is not greater than 100 nanometers.
