Rotating Drum Collector
In electrospinning, rotating collector is used to produce a uniform nanofibrous mat. This collection module consists of the rotating drum with a rotation speed control and display unit. Using this type of collector, randomly oriented nanofibers are deposited onto the surface of the drum.
The rotating wire collector is used to produce highly aligned nanofibers. It is composed of thin stainless-steel wires arranged at the same distance from the axis of the rotation. When the collector is rotating at very low speeds, fibers are also deposited between the conductive wires. The principle for the formation of aligned fibers is the same as in the case of the static patterned collector. At higher speeds, electrostatic and mechanical forces are combined, increasing the degree of alignment of the individual fibers. To achieve very good fiber alignment, the collector speeds could be much lower than those of the rotating drum collector.
