For Ti[O.sub.2]/ PLLA nanocomposites, the Ti[O.sub.2] nanoparticles affect the
crystallization process and the nucleation type is combination of heterogeneous and homogeneous process.
As an example, G' after a first increase during the cooling step, which can be ascribed to the effect of temperature, shows a plateau at T = [T.sub.c], followed by a second increase representative of the
crystallization process. Finally, a second plateau is found when crystallinity reaches a maximum value.
Crystallization process and POM analysis of PLLA/TTAD samples showed that the presence of TTAD accelerated the overall PLLA crystallization.
The result of a precipitation experiment is an image that is automatically generated and analyzed to determine the outcome of the
crystallization process (Jurisica et al.
Their knowledge of the
crystallization process as well as the oxidation process, ensures a quality, stable product every time.
The use of other constitutional units that interfere with the
crystallization process in the hard segments or improve the compatibility of the hard and soft segments (prevent phase separation) is a further means of creating transparent materials (chemical approach).
They have been able to observe differences in crystal form, distribution, and amount, as well as in the
crystallization process itself.
The first derivative is a picture of the actual solidification, and the area it contains is the energy being released by the
crystallization process. The second derivitive is used to pick out and magnify certain points on the overall curve that mark the beginning or end of a cooling phase.
The isothermal
crystallization process of SCF/PP was simulated using the combined model and the pixel coloring method proposed by Ruan et al.
Cold
crystallization process makes the form of crystal nucleus become easier, and the more crystal nucleus is, the more crystal of PLLA is, resulting in the increasing of melting enthalpy.
