Systematic analysis and nanoscale chemical imaging of polymers using photothermal-induced resonance (AFM-IR) infrared spectroscopy

In this work, a reliable and time-saving protocol for the measurement of polymers using photothermal-induced resonance (AFM-IR) at the nanoscale was developed and applied to 4 industrially relevant polymers: a polypropylene-based reactor thermoplastic polyolefin (rTPO), linear low density polyethyle...
