The study delves into the kinetics of non-isothermal crystallization Poly (ɛ-caprolactone) (PCL) and MgO-incorporated PCL nanofibers with varying cooling rates. Differential Scanning Calorimetry (DSC-3) was used to acquire information investigate behavior two types under different rates ranging from 0.5–5 K/min. results show that rate decreases at higher temperatures. Furthermore, parameters we...
Blends of polypropylene (PP) and polyamide 6 (PA6) with multiwalled carbon nanotubes (MWNTs) were prepared using different processing strategies in a twin-screw micro-compounder. The effect of MWNTs on the crystallization behaviour of the PP phase and the PA6 phase of the blend has been investigated through non-isothermal crystallization studies by differential scanning calorimetric analysis. F...
Laser Powder Bed Fusion (LPBF) of thermoplastic polymers is an additive manufacturing (AM) technique experiencing a remarkable growth in the recent years. Nowadays most widely used materials are polyamides (PA12, PA11…) but massively available LPBF-compatible polyolefin powders recently arrived on market. The need understanding crystallization process for these new essential and this was addres...
Nucleation and crystallization of polyamide 12 (PA 12) have been systematically investigated by fast scanning calorimetry at non-isothermal isothermal conditions. The critical cooling rates crystal nucleation were determined as 300 10,000 K/s, respectively. Moreover, the half-times (t1/2,nucl) overall (t1/2,cry) show monomodal bimodal dependencies on temperature. t1/2,nucl has an approximate mi...
