Yongbin Zhang*   Pages 1 - 5 ( 5 )


Background: The challenges to nanoporous filtration membranes are small fluxes and low membrane mechanical strengths.

Objective: To introduce newly invented nanoporous filtration membranes with complex pores with improved fluxes and mechanical strengths as registered in patents.

Methods: The analytical results are presented for the addressed membranes.

Results: The geometrical parameter values of the addressed membranes can be optimized for the highest fluxes.

Conclusion: The overall performances of nanoporous filtration membranes with complex cylindrical or/and conical pores can be significantly better than that of the conventional nanoporous filtration membranes with single cylindrical or conical pores.
