Abstract

Herein, a new high speed process for microcapsule generation in the field of medium-to-large-size capsules (0.2–5 mm) is reported which is rendered possible by combining three basic processing techniques in one system, namely the coextrusion technique, the vibrational nozzle technique and UV-curing. The versatility of the process is impressing, when it is combined with suitable materials. This is demonstrated for controlled release systems for concrete additives (superplasticizers) based on core–shell as well as matrix-type morphology that are assembled herein. It is shown that the process is highly flexible with respect to the material that can be encapsulated and, moreover, highly adjustable with respect to release mechanisms as these can be steered via the flexible choice of the shell materials. Eventually, the capsules can be created in a highly robust way and at remarkable throughput speed.
