This process enables fast andeconomic design of tailor-made structures. For implementation of additively manufactured structures in biocatalytic packed-bed reactors, a packing was designed topromote enhanced heat and mass transferto intensify the process. Still, these packings bear the challenge of low surface area,hence usage as a catalyst carrier is limitedso far. In order to overcome this bottleneck, re-sponsive polymers are investigated as surface enhancers. Surface enlargement is targeted by fixation of polymer brushes. Subsequently, enzymes are immobilizedon these polymers. Besides enlargement,the application of smart polymers intro-duces stimuli responsive behavior – coil-globule transition – as indicated in thefigure. Depending on the polymer, differ-ent triggers are possible, e.g., temperature, pH or substrate/product concentrations. Thus, autonomous process control byregulating the enzymes accessibility isprospective.1522-26402020912231223Conference Poster10.1002/cite.202055446Conference Poster
