This paper reports on the synthesis and characterization of a novel class of materials namely, photo-actuating and photo-rheological polymers. The terms photo-actuation and photo-rheological refer to the phenomena, where photo-responsive polymers undergo conformational changes upon UV irradiation. This conformational change can result in changes in the spectral and physical properties of the polymer. For example, its volume and rheological properties. The first part of this paper describes the laboratory-based synthesis and characterization of these materials. The second part describes the experimental methodology and results obtained when characterizing the photo-actuation and photo-rheological behavior of the materials. It was paramount in these experiments to control the temperature of the test specimen; this was necessary as some of the changes in the properties brought about by UV irradiation could also be accounted for by an increase in the temperature of the test specimen. Two classes of photo-responsive material were synthesized and characterized using conventional analytical techniques. The first series of polymers were polymethyl methacrylate (PMMA) based with azobenzene groups in the side chain, the second series contained spiropyran groups in the side chain. The characterization of the photo-rheological behavior of these materials involved the deployment of a custom-modified rheometer, which was operated under isothermal conditions. A liquid light guide was used to enable in-situ irradiation of the test specimen with UV or visible light. The photo-actuation studies involved experiments on liquids and solid films of the above-mentioned co-polymers. A commercially available 3-D surface profiler was used to study their photo-actuating behavior. A couple of unique apparatus were also designed and used to characterize the photo-actuation behavior of the polymers in solution. The effects of irradiation on the photo-rheological and photo-actuating behavior were quantified taking temperature effects into consideration. Potential end-use applications for these polymers are considered.

This paper reports on a comparative study undertaken for different types of optical fiber sensor developed to monitor the cure of an epoxy resin system. The optical fiber sensors used to monitor the cure process were based on transmission spectroscopy, evanescent wave spectroscopy and refractive index monitoring. The transmission sensor was prepared by aligning two optical fibers within a specially prepared sleeve with a gap between the optical fiber end-faces. During cure, resin from the specimen flowed into the gap between the optical fibers allowing transmission spectra of the resin to be obtained. The evanescent wave sensor was prepared by stripping the cladding from a high refractive index core optical fiber. The prepared sensor was embedded in the sample and attenuated total reflectance spectra recorded from the resin/core boundary. Refractive index monitoring was undertaken using a high refractive index core optical fiber which had a small portion of its cladding removed. The prepared sensor was embedded in the resin specimen and light from a single wavelength source was launched into the fiber. Changes in the guiding characteristics of the sensor due to refractive index changes at the resin/core boundary were used to monitor the progress of the cure reaction. The transmission and evanescent wave spectroscopy sensors were used to follow changes in characteristic near-infrared absorption bands of the resin over the range 1450 - 1700 nm during the cure reaction. Consequently these techniques required tunable wavelength sources covering specific wavelength ranges. However, the refractive index based sensor used a single wavelength source. Therefore the equipment costs for this type of sensor were considerably less. Additionally, the refractive index sensor did not require a single wavelength source at any particular wavelength and could be applied to any spectral region in which the optical fiber would transmit light. The advantages and disadvantages of these three methods are discussed.
