Cellulose as the most abundant natural polymer is renewable, biodegradable, biocompatible and is important in the manufacture of numerous products such as paper, textiles and pharmaceuticals. However cellulose is difficult to process in solution, because of its intra- and intermolecular hydrogen bonds. Typical cellulose processes are expensive and problematic environmental. Here, we report a single step approach for fabricating mineral oil-drop templated cellulose microstructures (microfiber, microtube, microcapsules) using a microfluidic. The production of oil-cellulose microstructures are based on the regeneration of cellulose from ionic liquid (IL) by simply contacting with water in a microchannel. Both the shape and size of mineral oil-drop and the morphology of cellulose were controlled by the flow rates of the mineral oil, cellulose solution with IL and water containing glycerol. The method is simple, fast, and environmentally-friendly compared to the previous methods. |
