Smart materials are highly desirable over the recent decade due to growing demand on complicated nature. with stable stimuli-responsive properties widely applied in sensors, smart windows, displays, and chemical valves, but they relatively rare. Most of current chromic triggered by one or two external stimuli, only a few multi-stimuli responsive instances still suffer their restricting function...

Fluorescence correlation spectroscopy (FCS) is a well-established technique for studying dynamic processes and interactions with minimal invasion into the corresponding system. Even though FCS has been mainly applied to biological systems, within the last 15 years an increasing number of studies in material sciences have appeared, demonstrating its enormous potential also for this field. Apart ...

We present a robust method to prepare thin oriented nematic liquid crystalline elastomer-polymer (LCE-polymer) core-sheath fibers. An electrospinning setup is utilized to spin a single solution of photo-crosslinkable low molecular weight reactive mesogens and a support polymer to form the coaxial LCE-polymer fibers, where the support polymer forms the sheath via in situ phase separation as the ...

Stimuli-responsive polymers and their application to biomaterials have been widely studied. On the other hand, as a novel biomimetic polymer, we have been studying the polymer with an autonomous self-oscillating function by utilizing oscillating chemical reactions. So far, we succeeded in developing a novel self-oscillating polymer and gels by utilizing the oscillating reaction, called the Belo...

Temperature responsive poly(N-isopropylacrylamide) (PNIPAM) exhibits a lower critical solution temperature (LCST) of approximately 32 °C in aqueous solution, below which the polymer is water soluble and above which it becomes water insoluble. The LCST of PNIPAM copolymer increases responding to hydrophilic block acrylic acid (AA). The copolymer is pH and temperature responsive. The duel respons...

A new method for the qualitative analysis of adenosine nucleotides (AMP, ADP, and ATP) and synthetic oligonucleotides has been proposed, utilizing a pH- and temperature-responsive polymer of N-isopropylacrylamide (NIPAAm), butyl methacrylate (BMA) and N,N-dimethylaminopropylacrylamide (DMAPAAm) as the stationary phase of HPLC. In the chromatographic system using the copolymer with ionizable gro...
