Novel Al2Mo3O12-PTFE composites for microwave dielectric substrates

Investigation on the improvement of microwave dielectric properties of plasma-prepared fluoropolymer-coated CaTiO3-filled PTFE composites

“…It has been proved that surface treatment with C 14 H 19 F 13 O 3 Si (F8261) can significantly improve the surface properties of ICAMIM-2023 Journal of Physics: Conference Series 2720 (2024) 012045 IOP Publishing doi:10.1088/1742-6596/2720/1/012045 2 ceramics, making them exhibit strong hydrophobicity. The modified ceramic surface, because the molecular structure (carbon-fluorine bonding) is similar to that of PTFE, can be a better bridge to establish with the PTFE and promote the formation of a compact structure [5][6][7] . However, these treatment methods are mostly chemical methods, which have the defects of complicated operation, harsh reaction conditions, low efficiency, and producing a large amount of waste organic solvents.…”

Fluorinated Polydopamine Shell Decorated Fillers in Polytetrafluoroethylene Composite for Achieving Highly Reduced Coefficient of Thermal Expansion

“…The incorporation of ceramic fillers with low CTEs is the most frequently used strategy to achieve the goal of CTE reduction in PTFE coating [4,5]. However, the severe aggregation of fillers and poor interfacial interactions between fillers and PTFE are the two main challenges for the PTFE composites due to the ultra-low surface energy of PTFE [6].…”
