Claims13
A composition, comprising:
- (A) water,
- (B) electroconductive nanoobjects,
- said electroconductive nanoobjects (B) having two external dimensions in the range of from 1 nm to 100 nm and their third external dimension in the range of from 1 μm to 100 μm,
- wherein said electroconductive nanoobjects (B) comprise one or more materials selected from the group consisting of silver, copper and gold,
- wherein a weight fraction of said electroconductive nanoobjects (B) is in the range of from 0.01 wt.-% to 1 wt.-% based on the total weight of the composition,
- (C) dispersed in the water, fibers of crystalline cellulose,
- said dispersed fibers (C) of crystalline cellulose having a length in the range of from 80 nm to 300 nm and a diameter in the range of from 5 nm to 30 nm,
- wherein the total weight fraction of said dispersed fibers (C) of crystalline cellulose is in the range of from 0.02 wt.-% to 5 wt.-%, based on the total weight of the composition.
