Technology of Evenly Dispersing PVDF (Polyvinylidene Fluoride)
Technology Background And Goals
The primary objective of this report is to evenly disperse PVDF (polyvinylidene fluoride) particles in a solution or matrix. PVDF is a highly non-reactive and pure thermoplastic fluoropolymer with excellent chemical resistance, thermal stability, and electrical properties. It has a wide range of applications, including lithium-ion batteries, sensors, and filtration membranes.
Achieving uniform dispersion of PVDF is crucial for optimizing its performance and ensuring consistent material properties. However, due to its semi-crystalline nature and strong intermolecular forces, PVDF tends to agglomerate, leading to uneven dispersion and compromised material quality. Overcoming this challenge requires a comprehensive understanding of PVDF's physicochemical properties and the development of effective dispersion techniques.
