Highly monodispered and porous oxime-functionalized cellulose droplets were prepaerd by microfluidic method. Cellulose was dissolved in N-methylmorpholine N-oxide (nMMO) monohydrate and the dope was used as the disperse phase. Mineral oil (EM 90, 3wt%) was used as the continuous phase. The achieved droplets were then washed with DI water. nMMO is miscible with water. After washing, the nMMO was removed and the droplets were mostly filled with water. After drying, the internal sturcture shrinked and could not swelled again due to the hornification of lyocell. But after cross-linking with epichlorohydrin, the droplets were not totally shrinked and porous sturcture was achieved. This cross-linked droplets were then applied to metal ions adorption by oxime functionalize. |
