Thermal behavior of molecular mobility obtained from spin-spin relaxation time, T 2, indicates that the hydrogen bond network formed in novolacs is predominant factor of glass transition for novolacs without cross-link agents. A representative chemical structure for a novolac is shown in Figure 1 from publication: A new material for bipolar plates used in fuel cells | The backelite-graphite composite material developed to meet the.
