“…This was supported by two separate melting peaks obtained from the second heating scan, corresponding to that of PP and PA6 at almost the same position in their respective bulk polymers. Ding et al33 highlighted the relationship between the droplet sizes and crystallization, stating that the different size of droplets containing heterogeneities of different activities will crystallize at different degrees of supercooling. The larger droplets containing active heterogeneities crystallize at higher temperature (lower supercooling) while the smallest droplets containing no heterogeneities (homogeneity) crystallize at a lower temperature (higher supercooling).…”

Boehmite alumina nanoparticles are added to PP‐g‐MAH‐compatibilized blends of PA 12 and PP to study the effects of nanoparticle loading in the resulting composites. WAXD and SEM data suggest that the nanoparticles enhanced the coalescence of PP. DSC, DMA, and TGA reveal that the final properties such as crystallization temperature, flexural storage modulus, thermal degradation temperature, etc., improve with increasing nanoparticle loading for blend/based composites. FTIR results show that the nanoparticles interfere with the interfacial activity at 5 wt% nanoparticle loading. All results are compared between the neat polymers and the compatibilized blend and show that despite a slight increase in dispersed‐phase domain size, all other properties improve with the addition of AlO(OH).

A composite of boehmite alumina nanoparticles and a PP/PA12 blend is prepared. WAXD and SEM suggest that a low filler loading enhances the coalescence of PA12, whereas a higher loading reverses the situation. DSC, DMA and TGA reveal that the final properties of the blend composites such as crystallization temperatures, flexural storage moduli, or thermal degradation temperatures improve with increasing nanoparticle loading. The data are compared with the neat polymers and the compatibilized blend, and the results show that the compatibility increases only at high nanoparticle loading, and most of the thermal properties improve with increasing nanoparticle content in the blends. The presence of interfacial interactions between the polymer matrices and the filler was confirmed via FTIR.

Development of exfoliated nanocomposite prepared from vinyl acetate and montmorillonite

To improve the chemical, physical, mechanical and thermal properties of polyvinyl acetate (PVAc), montmorillonite (MMT) was added and polymerised with vinyl acetate to prepare an exfoliated nanocomposite of PVAc-MMT. Linear macromolecular chains of PVAc were formed between MMT layers and they exfoliated MMT into layers or sheets of nanoparticles. Both PVAc and PVAc-MMT were pseudoplastic non-Newtonian fluids, and possessed the normal stress effect (or Weissenberg effect) that was the pole climbing phenomenon. PVAc-MMT's static tensile properties were better, and PVAc's glass transition temperature was lowered by MMT. Both PVAc and PVAc-MMT possessed cold crystallisation, and their pyrolysis were similar, because MMT had no obvious effect on pyrolysis temperatures but mainly delayed thermal degradation processes.
