Is Porous alumina membrane corrosion resistant?

ROCKFORD, Ala. - Aug. 16, 2017 - PRLog -- Porous alumina membrane's structure look like a single tube with multi-hole structure along with various controlled properties. Porous alumina main characteristic is corrosion resistance in both H2SO4 and NaOH aqueous solutions.AAO membranes with specific surface and pore size are applicable for molecular separation, tissue engineering, cell culture, bio sensing and drug delivery.

There are various different properties or variations in properties before and after corrosion of porous alumina support:

·         Mechanical strength

·         Open porosity and pore size distribution

·         Mass loss percent

·         Energy dispersive spectroscopy

·         X-ray diffraction

Porous alumina supports offer some potential applications are as follows:

1.      Micro Filtration or ultra filtration membrane supports

2.      Pre-treatment of strongly acidic industrial waste-liquids

3.      Corrosion resistance

4.      Decorative coatings

5.      Low flexural strength loss

6.      Polyaniline

7.      Nanowire

8.      Atomic layer deposition

9.      Anodic aluminium oxide

10.  Polypyrrole

11.  Nanotube

12.  Chemical vapor deposition and many more.

Porous aluminum oxide (http://www.topmembrane.com/en/lmxx.asp?id=26) is formed by electrochemical oxidation of aluminum in liquid electrolytes in the conditions that balance the growth and the localized dissolution of aluminum
