Eco-friendly process for facile pore control in thermally stable cellulose acetate utilizing zinc(II) nitrate for water-treatment
E-mail:
The generation of pores in cellulose acetate (CA) using water pressure and inorganic materials was investigated and succeeded in fabricating straight nanopores in polymer. In this study, we researched Zn (NO3)2ㆍ6H2O to have relatively larger ionic size instead of Ni(NO3)2ㆍ6H2O. When the CA/Ni(NO3)2ㆍ6H2O membrane was employed, the water flux was about 95 L/m2 h at water-pressure of 8 bar. However, the water flux through the CA/Zn(NO3)2ㆍ6H2O membrane was about 182 L/m2 h at the same water-pressure. This indicated that Zn(NO3)2ㆍ6H2O was more easily able to control the pore size than Ni(NO3)2ㆍ6H2O since both zinc salts and the plasticized parts by salts were readily removed by water-pressure.
