Poor hydrophilic modification effect of PVDF microporous membranes
Fenómeno del problema
The water flux decays quickly after hydrophilic modification
Análisis de la causa
The bonding force between the hydrophilic coating and PVDF is insufficient and the crosslinking is not enough
Solución
Blend hydrophilic polymers, in-situ polymerization
Conclusión clave
The long-term stability of membrane hydrophilic modification is the key
