Influence of temperature and pH on thermoresponsive PNIPAM films.

Germany / Германия

During the last decades microgels made of N-isopropylacrylamide (NIPAM) have attracted much interest and were studied by techniques like microscopy and light scattering. These polymer particles show a thermoresponsive behaviour and can therefore be classified as “smart” materials. The PNIPAM films were prepared by spin coating and dip coating methods. The film characterisation has been done using Atomic force microscopy (AFM) and ellipsometry. The results show that the way of preparation and external stimuli like pH and temperature influences strongly the film structure.
