Al-Rasheed R., Davis B., Diep J., Dubois G., Freeman B., Geise G., Na Y.-H., Nassar M., Vora A., IBM Almaden Research Center, US
We have developed polyamide bi-layer thin film composite membranes to enhance RO-desalination performance. The polyamide bi-lyer membrane consists of conventional non-substituted aromatic polyamide under-layer and HFA-substituted aromatic polyamide top-layer, which can be esaily prepared by [...]
