To date, majority shape adaptations of shape memory polymer (SMP) are thermo responsive. A desire for isothermal,
remotely controlled shape adaptations of SMP has motivated examinations of other stimulus. We successfully construct
novel TiO<sub>2</sub>-polystyrene shape memory nanocomposites and investigate influence of the ultraviolet irradiation on the
shape memory effect. This material is facilely fabricated by introducing TiO<sub>2</sub> into polystyrene SMP. The properties of
TiO<sub>2</sub>-polystyrene shape memory nanocomposites are characterized by X-ray powder diffraction (XRD), Fourier
transform infrared spectra (FT-IR), dynamic mechanical analysis (DMA), and diffused reflectance spectrum (DRS).
Deriving from photoelectric foundational properties of TiO<sub>2</sub>, the TiO<sub>2</sub>-polystyrene shape memory nanocomposites can
absorb light energy and undergo intra-molecular or inter-molecular physical or chemical transformations. Furthermore,
the results of this work provide a useful baseline upon which researchers could explore more interesting behaviors of
photosensitive SMP composite and investigate other more challenging actuation problems.
