“…This improvement in ductility with lignin addition can be attributed to both lignin plasticization effect and miscible blending between PA6 and lignin. Such a behavior has already been observed for partially miscible blend of polyvinylidene fluoride and polytetramethylene adipate . According to the authors small concentrations of polyester modify the lamellar microstructure and act as a plasticizer.…”

Sailaja et al have demonstrated the same effect in a compatibilized composite of polyethylene and modified lignin via an esterified route.…”

Environmentally friendly bio-filled composites of various proportions of polyamide 6 (PA6) and technical lignin have been prepared using a twin-screw extruder. Transmission electron microscopy has been used to investigate the morphology of the composites. It reveals homogeneous single phase system, indicating the miscibility of PA6 and lignin. The glass transition temperature of the blends, determined by DMA, was shifted systematically to higher temperature with increasing concentration of lignin which highlights the miscibility of both components. In addition, Fourier Transform Infrared analyses have shown that new specific hydrogen-bonding interactions are formed between hydroxyl groups of lignin and amine groups of the PA6. The presence of these intermolecular interactions between PA6 and lignin strongly influenced the thermal stability of the blends by lowering the onset of the blend's degradation process. However, the blends exhibit good mechanical properties whatever the lignin content.

“…According to this (a) E-mail: Leizhang20@gmail.com model, the nanoscale phase separation is related to the hydrogen bonding and size-dependent surface tension intimately. Consequently, we expect that this intrinsic nanoscale behavior will appear in other miscible polymer blends with interphase interactions, such as hydrogen bonding and strong electrostatic interactions [13][14][15].…”

Intrinsic nanoscale phase separation in polymers is demonstrated experimentally and theoretically for the first time. Dense stable nanodots with size ≈ 80 nm have been created over large areas in polymethylmethacrylate and poly(vinylidene fluoride-trifluoroethylene) blend films, and a model is developed to show that the intrinsic nanoscale phase separation is related to the hydrogen bonding and size-dependent surface tension intimately.
