In this study, because of the homogeneous and fine dispersion of silica nanoparticles, it seemed that the 3 wt% loading was an optimal silica loading for the P (3HB-co-4HB) nanocomposites with the best performance such as the good crystallizability
and the thermal stability, and the optimal mechanical properties as discussed below.
In this study, we elucidate further the cold crystallization behaviors of FDPLLA comparing with a bulk amorphous PLLA, perform structural characterizations by means of wide-angle X-ray scattering (WAXS), Fourier transform infrared (FTIR) spectroscopy, and density and specific surface area measurements, and try to understand the origin of the high crystallizability characteristic to the FDPLLA.
It is pertinent to assume that the high crystallizability of FDPLLAs is originated from higher mobility of the polymer chain which is specific to the freeze-dried state with high surface-to-volume ratio as will be discussed in the next section.
However, PP exhibits very poor compatibility and low adhesion to other polymers and inorganic fillers due to its nonpolarity and crystallizability.
c] is then a good indication of the crystallizability or crystallization rate.
m], suggest an increase in the crystallizability
of PPS matrix in the presence of MWCNTs.
To compare the crystallizability
of the PP and PP/[CaCO.
However, conflicting results were reported in the literature concerning the effects of TLCP on the crystallizability
of crystalline thermoplastic in thermoplastic/TLCP composites (2), (3).
o] signifies the inherent crystallizability of the polymer, being the degree of supercooling required in the limit of zero cooling rate, and the slope P indicates a process sensitivity factor.
3] will induce more nuclei and have higher crystallizability.
