In today's world, amorphous conducting polymers are extremely important in technology. Due to its lightweight, transparency, and long-lasting mechanical performance. They are finding applications in the aerospace, automotive, and military sectors, thus adequate precision-based research are required. The nanoindentation P-h plots of PPy were examined based on load fluctuations observed at specific depth intervals. The observations were used to explain polymeric chain motions and visco-elastic-plastic flow.
