BLUE light has been used by researchers to create an interpenetrating polymeric network (IPN) in one step, under ambient conditions.
When linked together, two or more polymer chains with different mechanical properties can form IPNs. This resulting network is not bonded through chemical means, instead polymer chains are entangled and cannot be pulled apart. Subsequently, material performance can be enhanced, with applications including ion exchange resins and medical dressings. However, the process of linkage typically requires a lengthy two-step process or a one-step process requiring high temperatures.
