In this review, we show that reversibility of charge storage occurs in polymers with bistable redox-active groups populated in the repeat units of a nonconjugated backbone, especially when an electron self-exchange reaction spreads throughout the polymer. We will also show that extending the idea ...
Secondary nucleation is an approach to synthesizing higher-order supramolecular polymers with exciting topologies, but a detailed understanding of growth processes is needed. Here, the authors report the non-covalent synthesis and high chiro-optical photoresponse of dendritic homochiral superstructures via ...
For a thin film of PVK-C60 sandwiched between an indium tin oxide (ITO) electrode and an Al electrode (ITO/PVK-C60/Al), the device behaved as nonvolatile flash (rewritable) memory with accessible electronic states that could be written, read, and erased. The polymer memory exhibited an ON...
Non-isocyanate rigid polymer foams by carbon-Michael addition and foaming processPolymer foam is made from a two-component foam system. The foam system includes an A-side component which contains a multifunctional Michael acceptor and a ... J Xin,Steven P. Crain,Deborah A. Schutter,... 被引...
Fiber, fabric, and nonwoven fabric To provide: a fiber having excellent adhesiveness, which is able to be bonded to a polar resin, a resin containing an inorganic filler (especially a glass fiber), a ceramic, glass, a metal or the like, without being subjected to a primer... USA (A)...
Polymer networks are molecular-based systems, whose network structure depends upon covalent or non-covalent interactions between macromolecules. The interactions can be simple covalent cross-links, or more complex junction zone or particulate-type interactions. Figure 1.1 illustrates different types of poly...

In essence, the network is in this case permanently deformed (non-recoverable) from the standpoint of thermodynamics, and the residual strain would be observed (illustrated in Fig. 4d and Supplementary Fig. 26d, e)47. In addition, the cleavage and reconstruction of TAD-indole adducts reaches ...
1c), which is typical for diffractions from non-flat crystals due to the inevitable lattice splay in curved space7,13,35,43,44,45. This can also be viewed as packing of small crystallites progressively changing lattice orientation as the crystal grows. The spherical shape can be better ...
