Table 1.

Maximum pore size of alumina/polymer membranes with different CNTs loadings.

Sample	Pressure When the First Bubble Appeared (kPa) *	Maximum Pore Size (nm)
Pristine	200	178
0.2 wt % CNTs	205	174
0.5 wt % CNTs	240	148
1.0 wt % CNTs	245	145

Notes: * The pressure showing in this table is the average value of two tests and the standard error is within 10 kPa.
