Photocontrollable Liquid Crystalline Polymer Actuators
By incorporating azobenzene groups into the crosslinked liquid crystal polymers (CLCPs),
large deformations such as contraction and bending have been induced by UV light due to the
photoisomerization of the azobenzene chromophores. Since light is an ideal stimulus for it can be
localized (in time and space), selective, nondamaging, and allows for remote delivery of energy,
photodeformable CLCP...

Polymerization of & in ionic liquid-based microemulsions
Ionic liquids (ILs) are attracting significant attention in many fields of chemistry and industry because of their unique physicochemical properties, such as negligible vapor pressure, low volatility, high thermal stability and ionic conduc...

Viscoelasticity of pullulan in ionic liquid BmimCl
Ionic liquid is an Organic salt which is liquid state at room temperature. Recently, it has been reported that the ionic liquid, 1-butyl-3-methylimidazolium chloride (BmimCl) can dissolve the insoluble polysaccharides such as cellulose.

Rheological behavior of cellulose in ionic liquid
Since Swatloski etc 1 reported that ionic liquids (ILs) are nonderivatizing solvents for cellulose, ionic liquids are known as another green solvent for processing cellulose fibers except for N-methylmorpholine-N-oxide (NMMO).

Foam films obtained with ionic liquid
Herein, we report the unprecedented properties of foamfilms o btained with an ionic liquid. Centimeter-scale foam films of nonionic surfactants were prepared by using 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIM][BF4]) as a solvent, and they were transferred onto submillimeter-sized holes. The films spontaneously became thinner, and
finally reversed bilayers solv...

Photorefractive surface waves in liquid crystal
We predict the formation of electrically and optically controlled photorefractive surface waves iin liquid crystal, with orientational photorefractive effects. In contrast to the case for photorefractive surface waves in inorganic crystals, the penetration depth of photorefractive surface waves in liquid crystal can be controlled by means of the applied external electric field, wh...

Ionic Liquid of Ultralong Carbon Nanotubes
In summary, 100–500-nm-long MCNTs with an ionic liquidlike behavior and an excellent thermal stability were obtained. An approximately 6.5-nm-thick shell model with an ionic, perpendicular bilayer structure on the CNT surface was verified. This finding will offer a new practical method to process “solid CNTs” or polymer–CNT composites, such as macromolecules, colloid...

UV-curable epoxy systems containing hyperbranched polymers: Kinetics investigation by photo-DSC
关键字：Epoxy resins,Photopolymerization,Photocalorimetry
The effect of the presence of a hyperbranched OH-functionalized polymer (HBP) on the kinetics of cationic photopolymerization of an epoxy system was investigated employing two complementary techniques, photo-DSC and real-time FT-IR spectroscopy....

Rheological Properties of PEPA End-capped Polyimide Resins based on Isomeric HQDPAs
关键字：Rheological Properties, PEPA, Polyimide
This is a continuation of our series work on “Isomeric Polyimide”. NASA Langley Research Center in USA has reported excellent work on phenylethylyl end-capped aromatic polyimides based on 3,3’,4,4’-bipnehyl dianhydride (4,4’-BPDA) and ...
