“…The lignin–PET interactions disrupt the integrity and purity of PET spherulites and induce a drop in the melting temperature of the polyester. Similar behavior has been reported for the blend of lignin with poly(lactic acid) . These results provide therefore strong support to the hypothesis that lignin and PET exhibit good miscibility, and agree with previous observations for the same polymers …”

“…The T cc of pure PET generally appears in the region between 100 °C and 160 °C, while its T g is generally between 70 °C and 80 °C . On the other hand, the T g of lignin generally varies depending on its source, while it does not exhibit any melting temperature since it is amorphous because of its complex structure . Here, the T g of lignin appears at approximately 88.7 °C.…”

“…Significant attempts have been made to employ lignin in polymer blends to achieve CFs having improved processability and strength. In one study, Wang, et al blended fractionated commercial hardwood thiolignin with poly(lactic acid) (PLA) in varying ratios [40]. After extrusion at 220-240 • C, initial thermal stabilization was accomplished by heating to 280 • C at a rate of (0.05 • C/min) followed by carbonization by heating to 1000 • C at 3 • C/min.…”

“…13,14,33 It is worth noticing that the uniform diameters and lack of structural defects obtained by optimal thermostabilization are critical to increase the mechanical properties of carbon bers. However, to achieve these good mechanical properties, precursor bers have a relatively low heating rate and long preparation time during thermostabilization to prevent the melting and deformation of lignin-based stabilized bers (SFs), 34,35 which lead to higher energy consumption, compared with just PAN precursor carbon bers. 24,25 Therefore, increasing the heating rate and reducing the preparation time in thermostabilization has become a major challenge.…”
