Patent ID: 8029700

Claim:
A compound of a thickness T (in μm), a resistivity R (in Ohm·m), a product of an average resistance Ra of the compound and T, and a content C (in wt %) of silver nanowire with polymer, comprising: a resin; a dispersant copolymerizing with the resin, the dispersant comprising a plurality of dispersant monomers, and each of the plurality of dispersant monomers including one or more chelating functional group; and a plurality of silver nanowires; connecting, in chemical bond to the plurality of chelating functional groups, respectively, and dispersing in the resin, wherein i) the plurality of silver nanowires are evenly distributed without clotting together in dendrites or blocks in SEM image of the compound when the content C of silver nanowire is 67; and ii) C and R are in a negative linear relationship (anticorrelation), given C ranging from 49 to 69 in an increasing order, and given T ranging from 88.8 to 21.9 in a decreasing order.
