Organic electrode materials are finding increasing use in energy storage devices due to their attractive properties that allow building of flexible and low weight devices in an environmentally friendlier manner than traditional alternatives.

This is due to the advantageous synergy between CP and PG, e.g. electronic conductivity, high stability and large charge storage capacity. In this thesis pol

Abstract:

Recent biosensors using glucose oxidase enzyme to detect glucose (“blood sugar”) were made with intrinsic conducting polymers such as poly pyrrole (PPY) to mediate the reaction. PPY coated electrodes were difficult to employ via eletropolymerization because PPY is only soluble in solvents potentially damaging to enzymes. Nano crystalline cellulose – poly pyrrole (NCC-PPY) colloid circumvents this by forming natural, enzyme compatible, and hydrophilic films mechanically bound to electrodes using easy-to-disperse colloids.
