Microstructural and mechanical characteristics of compatibilized polypropylene hybrid composites containing potassium titanate whisker and liquid crystalline copolyester

Synthesis of potassium polytitanate precursors by treatment of TiO2 with molten mixtures of KNO3 and KOH

“…The influence of K 2 CO 3 admixture (3.5 mol.%), introduced into the molten system of KNO 3 3.1), on the kinetics of the potassium titanates formation in comparison with the data for the series 2.2, is presented in Fig. 5.…”

“…The introduction of K 2 CO 3 increases the concentration of O 2− ions, as a result of CO 3 2− ions decomposition, 8 and accelerates formation of TiO 3 2− ions in the melt (processes 2 and 3). However, this favors the potassium polytitanate formation only after the induction period (curves 1 and 2 in Fig.…”

“…This type of materials is an alternative to silicon carbide, taking into account its lower price. [1][2][3][4][5][6] On the other hand, potassium titanate powders could be used to produce ceramics characterized with high mechanical properties and thermal resistance. However, the production of such powders (for example, K 3 Ti 9 O 13 , K 2 Ti 6 O 13 ) is based on multistage methods that involve sintering at high temperatures (1000 • C).…”

Introduction to the composite and its toughening mechanisms

“…For example, whiskers of silicon nitride are being made as fine as 0.2-0.5 mm in diameter. Tjong and Meng (1999) found that whiskers could have much higher specific strength than short glass or carbon fibers and could reinforce polymers more effectively.…”

Micro-Rheological Study on Fully Exfoliated Organoclay Modified Thermotropic Liquid Crystalline Polymer and Its Viscosity Reduction Effect on High Molecular Mass Polyethylene

“…Rheological characterization revealed that TLCP could reduce the melt viscosity of glass-filled thermoplastics [6]. Much work has been published on TLCP systems containing different inorganic solid reinforcements, such as glass fibres [7], carbon black [8], whiskers [9] and silica [10]. Most of the studies have used high inorganic solid reinforcement content and have focused on the balance between the mechanical properties and processability of such blends.…”
