Hydrogel nanocomposites are attractive biomaterials for numerous applications including tissue engineering, drug delivery, cancer treatment, sensors, and actuators. Here we present a nanocomposite of multiwalled carbon nanotubes MWCNT and temperature responsive Nisopropylacrylamide hydrogels. The lower critical solution temperature LCST of the nanocomposites was tailored for physiological applications by the addition of varying amounts of acrylamide AAm. The addition of nanotubes contributed to interesting properties, including tailorability of temperature responsive swelling and mechanical strength of the resultant nanocomposites. The mechanical properties of the nanocomposites were studied over a range of temperatures 25–55°C to characterize the effect of nanotube addition. A radiofrequency RF field of 13.56 MHz was applied to the nanocomposite discs, and the resultant heating was characterized using infrared thermography. This is the first report on the use of RF to remotely heat MWCNThydrogel nanocomposites. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010 [ABSTRACT FROM AUTHOR] |
