batteries and
supercapacitors to improve energy density and charge/discharge rates.
Sensors: The sensitivity and specificity of nanomaterials make them ideal for detecting various environmental and biological signals.
Flexible Electronics: Conductive polymers and nanomaterials enable the creation of bendable and stretchable electronic devices.
Chemical Vapor Deposition (CVD): Commonly used for the production of graphene and CNTs, this method involves the deposition of gaseous reactants onto a substrate.
Sol-Gel Process: This technique is used to create metal nanoparticles by transitioning a sol (a colloidal solution) into a gel-like network.
Electrochemical Deposition: Used for coating surfaces with thin layers of conductive materials, this method involves the reduction of metal ions onto a substrate.
Polymerization: Conductive polymers are synthesized through chemical or electrochemical polymerization of monomers.
