The maximum capacitive energy stored in polymeric dielectric capacitors, which are ubiquitous high-power-density devices, is dictated by the breakdown strength of polymer. fundamental mechanisms breakdown, however, remain unclear. Based on a simple free-volume model polymer fluid state, we hypothesized that free ends linear chains might act as "defect" sites, at can initiate. Thus, cyclic polymers should exhibit enhanced stability comparison to their counterparts having same composition and...
Abstract The dissimilarity of material composition in existing stretchable electronics and biological organisms is a key bottleneck, still yet to be resolved, toward seamless integration between species. For instance, human or animal tissues skins are fully made out soft polymer species, while composed rigid inorganic materials, either purely partially. Soft polymeric materials with intrinsic softness stretchability sought after therefore proposed address this technical challenge. Here,...

To utilize the full potential of block copolymer (BCP) thin films for use in technological devices ranging from ion conduction membranes and transistors to nanowire array antennas, rapid self-assembly lamellar copolymers (l-BCPs) with vertically oriented domains on a variety unmodified substrates is needed. l-BCPs have an inherently larger interfacial area transport compared their cylindrical counterpart. Our observations demonstrate that as-cast weakly ordered state l-BCP...
Previous studies have shown that the degree of ordering and alignment in block copolymer (BCP) films can be enhanced by increasing thermodynamic driving force for microphase separation, χN, where χ is Flory–Huggins interaction parameter between polymer components N number statistical segments BCP. In practice, this strategy controlling microstructure any BCP film normally involves reducing temperature T and/or N. However, both these methods drawback leading to a corresponding slowing down...
