Influence of surface modification of potassium polytitanates on the mechanical properties of polymer composites thereof

Epoxy composites modified with microfibers of potassium polytitanates

“…Despite wide prospects for their practical application, comparatively little attention has been paid to the synthesis, study, and application of a relatively new class of ceramic materials: potassium polytitanates (PPTs) …”

“…The structure and properties of polytitanates depend significantly on the composition of the initial components, the K 2 O/TiO 2 ratio in the molecule, and the conditions of synthesis. Depending on the conditions of synthesis, PPTs can form amorphous or crystalline structures with particles of different morphologies, from a layered scalylike form, nanofibers and microfibers with different cross‐sectional shapes, to hollandite‐like tunnel structures …”

“…Because of their properties, PPTs can be used as relatively inexpensive fillers of polymer–matrix and metal–matrix composites with high mechanical strengths, reduced coefficients of friction, and high thermal stabilities …”

“…The influence of PPTs with amorphous layered structures on the performance characteristics of epoxy composites has been studied earlier …”

Polytetrafluorethylene‐based high‐k composites with low dielectric loss filled with priderite (K1.46Ti7.2Fe0.8O16)

“…On the other hand, sintered ceramic materials based on modified potassium polytitanates (PPTs) and represented by hollandite‐like solid solutions (K 1.46 Ti 8‐x Me x O 16 , Me—transition metal) exhibit permittivity at level of the world's best performance ceramics ( ε' = 10 5 –10 7 at 10 −2 Hz frequencies and ε' = 10 2 –10 3 at 1 MHz) . In our previous works, the efficient interaction between polymer matrix and surface of the PPTs particles and high mechanical strength of polytitanate‐based composites has been shown . That is why they can be considered as promising fillers for the PTFE‐matrix functional composites.…”
