1. A method of making a poly(3-aminopyrazole-4-carbonitrile) comprising the steps of:
adding water to a flask;
adding potassium hydroxide to the water in the flask;
stirring the potassium hydroxide and the water in the flask;
dissolving the potassium hydroxide in the water in the flask and making a first solution;
adding 3-aminopyrazole-4-carbonitrile to the first solution;
heating the 3-aminopyrazole-4-carbonitrile in the first solution;
dissolving the 3-aminopyrazole-4-carbonitrile in the first solution and forming a second solution;
adding sodium or potassium persulfate to the second solution; and
forming an electrically conducting poly(pyrazole);
wherein the electrically conducting poly(pyrazole) comprises poly(3-aminopyrazole-4-carbonitrile); and
wherein the length of the polymer is a 15-mer.
