FAbrication and thermoresponsive
properties of thin copolymer films of poly-N-isopropylacrylamide and
acrylamide
Abstract
Abstract. A new technique for fabrication of thin poly-N-isopropylacrylamide and
acrylamide copolymer films on glass and silicon is proposed. The methodology is
based on pre-copolymerization of monomers followed by crosslinking of polymer
chains during spin-coating. The effect of temperature on hydrophobicity of the
obtained films is studied. Reversible changes of the contact angle are
demonstrated upon temperature variation above and below 35 °C.
Key words: stimuli-responsive polymers,
thermoresponsive polymers, poly-N-isopropylacrylamide, PNIPAm, wetting, thin
films
