Abstract

The mold temperature dependence of bisphenol A polycarbonate (BPAPC) in the view of changing the “flexed state” was investigated by mid-infrared spectroscopy combined with a previously developed thin sample preparation system. The differences in the samples of different mold temperatures were clearly detected. The structural changes in the flexed state of each mold temperature were analyzed by comparing the results using dielectric function analysis of different cutting procedures. Some structure parameters were associated with the contact angle of liquids on polymer plate. The evidence suggests that mold temperature and surface wettability affects the cohesive or entanglement state of polymers at the chemical structure level.
