Abstract

This work shows a simple way of producing fixed bed microreactors or packed microcolumns by using electrodynamic focusing. Based on previous results that showed fibre focalization on orifices is possible, we explored this technique to electrospun fibres inside microchannels. Different polymeric nanofibres - either neat or composite, i.e. fibres containing particles - can be deposited without meaningful difference on deposition parameters, resulting in packed structures. Moreover, distinct substrates can be used for mask production, which can be reused with the respective setup. Finally, the use of a dry process shortens the process time, increasing productivity.

采用电动力聚焦技术制造嵌入纳米纤维的微反应器
本工作展示了一种利用电动力聚焦生产固定床微反应器或填充微柱的简单方法。基于先前的结果表明纤维聚焦在孔上是可能的,我们探索了这种技术在微通道内的电纺纤维。不同的聚合纳米纤维——无论是整齐的还是复合的,即含有颗粒的纤维——都可以在沉积参数上没有明显的差异,从而产生堆积结构。此外,不同的基材可以用于掩膜生产,可以在各自的设置中重复使用。最后,干法的使用缩短了加工时间,提高了生产率。
