- One use here is, for example, the connection to glass.
- linkers were applied to etched glass surfaces, which in turn serve as an anchor group for the functional polymers.
- a disadvantage of the process described is that the application of the functional polymers requires that the surface or region to which the functional polymers are attached be in a solid state. If, for example, on a surface to be protected from dirt or easily to be cleaned surface further functionalities such. Protective layers are to be applied, a multi-step process is necessary because the functionalization with the stimuli-responsive coating is possible only after curing of the surfaces to which the polymers are to be connected directly.
- the linking by the provision of a linker is also usually a multi-step process, which is time-consuming and time-consuming.
- the alternative method is growing the functional polymers on a linker surface. This process is complex and takes a relatively long time.
