Several materials are employed to create flexible substrates, including:
1. Polymers like polyimide, polyethylene terephthalate (PET), and polyethylene naphthalate (PEN). 2. Metal foils such as copper and aluminum. 3. Organic materials like organic photovoltaics and organic light-emitting diodes (OLEDs). 4. Nanocomposites that combine nanoparticles with flexible matrices for enhanced properties.
