Conventional polymer dispersed liquid crystal (PDLC) films have been successful as electrically-switchable screens for privacy applications. However, spatial patterning of the so to generate a visually appealing design, logo, or image typically requires intricate fabrication processes, such use prefabricated photomasks that do not allow on-demand designs. Herein is reported on and characterizat...
Liquid phase homogeneous reactions using soluble polymer supports have found numerous applications in homogeneous catalysis and organic synthesis because of their advantages of no interface mass transfer limitation and a high conversion rate. However, their application in analytical separation is limited by the inefficient/inconvenient recovery of the target molecules from the extremely complex...
Introduction The conformation of a polymer chain is very sensitive to changes in the surrounding environment. When polymer chains are chemically tethered at one end to a stiff solid substrate or interface with a sufficiently high grafting density, the chains avoid overlapping and stretch along the surface normal to form a polymer brush layer. Thus, substrates and interfaces can be modified with...
Förster resonance energy transfer (FRET) may be regarded as a "smart" technology in the design of fluorescence probes for biological sensing and imaging. Recently, a variety of nanoparticles that include quantum dots, gold nanoparticles, polymer, mesoporous silica nanoparticles and upconversion nanoparticles have been employed to modulate FRET. Researchers have developed a number of "visible" a...
Responsive polymer-based materials (or smart materials) have found numerous uses over the years due to their ease of synthesis and various responsivities/functionalities. Of them, stimuli-responsive hydrogel particles (microgels) have generated a lot of interest, and have been used for a number of applications, most importantly for this submission is their use as components of photonic material...
