Researchers from Technion–Israel Institute of Technology have studied the kinetics of polymerization under confinement.
Experimental results show that the polymerisation kinetics are different inside a core–shell electrospun nanofibre compared to the bulk. The reaction rate decreases when the mean size of the clusters approaches the size of the internal fibre diameter. This causes the polymerisation reaction to become polychromatic, where the rate of reaction decreases with time.
