Poor hydrophilic modification effect of PVDF microporous membranes
Fenómeno do problema
The water flux decays quickly after hydrophilic modification
Análise das causas
The bonding force between the hydrophilic coating and PVDF is insufficient and the crosslinking is not enough
Solução
Blend hydrophilic polymers, in-situ polymerization
Conclusão principal
The long-term stability of membrane hydrophilic modification is the key
