Characteristically, polymers consist of the long chain molecules constructed of atoms (such as carbon and hydrogen) in the various arrangements with the different elements in the forming of basic building block of a polymer chain. Besides its primacy to the safety and environmental issues, polymer is becoming more widely used in today's industrial products due to its inherent advantages, such a...

As a model of soft confinement for polymers, we investigated equilibrium shapes of a flexible vesicle that contains a phase-separating polymer solution. To simulate such a system, we combined the phase field theory (PFT) for the vesicle and the self-consistent field theory (SCFT) for the polymer solution. We observed a transition from a symmetric prolate shape of the vesicle to an asymmetric pe...

We have investigated conformational properties of a linear semiflexible homopolymer chain in the bulk and adsorption desorption behaviour in the presence of an attractive impenetrable curved surface using lattice models. Since, it is understood that the essential physics associated with the conformational behavior of such polymer chains can be derived from a model of a self avoiding walk (SAW) ...

Interest in organic and polymer light-emitting devices (OLEDs and PLEDs) has exploded in recent years, in part because of the ability to create these devices on flexible plastic substrates. This is advantageous in producing wearable or lightweight displays, as well as utilizing low-cost roll-to-roll processing techniques. For the first time, we present crystalline refractory inorganic thin film...

This paper demonstrates a novel and low-cost additive manufacturing process for flexible and disposable microfluidics on virtually any substrate, with which the first “all-inkjet-printed” microfluidic microwave sensor is prototyped. A 30-μm-high 600-μm-wide SU-8 (polymer) 3-D microfluidic channel and an electromagnetic sensing setting are fabricated with sole reliance on multilayer inkjet-print...

This study investigates novel deposition techniques for the preparation of TiO2 electrodes for use in flexible dye-sensitized solar cells. These proposed new methods, namely pre-dye-coating and codeposition ultrasonic spraying, eliminate the conventional need for time-consuming processes such as dye soaking and high-temperature sintering. Power conversion efficiencies of over 4.0% were achieved...

In this work, we report on a flexible triboelectric generator (TEG) with multilayer polymer structure, consisting of poly(vinylidene fluoride-co-trifluoroethylene) (PVDF-TrFE) layer sandwiched by polydimethylsiloxane (PDMS) layers for the performance enhancement TEGs. We confirmed that output TEG is closely dependent structure and polarization direction PVDF-TrFE layer. addition, PDMS serves as...

Boronic acid affinity gels are important for effective separation of biological active cis-diols, and are finding applications both in biotech industry and in biomedical research areas. To increase the efficacy of boronate affinity separation, it is interesting to introduce repeating boronic acid units in flexible polymer chains attached on solid materials. In this work, we synthesize polymer b...

Strain gauges are widely applied to measure mechanical deformation of structures and specimens. While metallic foil gauges usually have a gauge factor slightly over 2, single crystalline silicon demonstrates intrinsic gauge factors as high as 200. Although silicon is an intrinsically stiff and brittle material, flexible and even stretchable strain gauges have been achieved by integrating thin s...
