1 An interesting radiolarian -like silica spherulite was prepared from a water-diethyl ether binary solvent system, which is characterized by SEM, TEM, XRD, and adsorption experiments.
2 It has been found that the growth of spherulite is determined by the competition of two factors: the rate of phase separation of the components and the rate of crystal growth.
3 The morphology of spherulite and mat-crystal structure in PPTA films coagulated from pure sulfuric acid solutions under different conditions has been studied by light scattering method.
4 The causes for the formation of ring spherulite were explained.
5 At a slow cooling rate, the size of spherulite becomes larger and more regular.
6 The anhydrite caused spherulite size of PP diminishing, the quantity increasing.
7 In the uniaxial orientation, the i PP spherulite, the lamella, and the molecular chain were subject to deformation in response to the imparted stress.
8 The small size of spherulite was formed in modified nanocomposites.
9 The methods of decreasing spherulite size of polypropylene, such as adding nucleating agents, blending with other polymers and temperature control were introduced.
10 POM showed that the spherulite size of PA66 was larger than that in neat case and that the spherulites became gradually irregular with increasing TLCP content.
11 The spherulite growth behaviour of hard segment has been studied by SALS and other techniques for polyester-polyether block copolymers with low hard segment content.
12 The spherulite morphology of PA1010/6 crystallizing at different conditions was studied by PLM and SEM.
13 This means that large fibrous structures form near T m, whereas greater numbers of small spherulites grow at lower temperatures.
14 It ones to the conclusions that the crystallization induction period and spherulite appearance time of PTT are approximate to PBT but different from PET.
15 POM results show that the dispersed morphology of MH plays an important role in the crystalline morphology and spherulite size of PP crystals.
16 The results showed that MB could improve the mechanical properties of PP. At the same time, MB could decrease the spherulite size and the crystallization degree of polypropylene.
17 In the present paper, SALS, PLM, DSC,(www.Sentencedict.com) WAXD and SEM were used to investigate the mechanism of spherulite formation of copolyether polyurethanes by melt annealing.
18 The HDPE was drawn in the die, its morphology is changed from spherulite structure of original material to fibrillar structure.
19 Polarized optical images of the gels show that the aggregates of the three gelators are spherulite crystallite and other types of crystallite inn- octanol .
20 The authors discovered directional arrangement of feldspar and mica microcrystals and elongated spherulite in the hight-p experimental products.
21 Organic nucleators, sodium benzoate, NA2002 and zirconium stearate, can decline the spherulite size and increase the properties of PP.
