The introduction of molecularly woven three-dimensional (3D) covalent organic framework (COF) crystals into polymers varying types invokes different forms contact between filler and polymer. Whereas the combination COFs with amorphous brittle polymethyl methacrylate results in surface interactions, use liquid-crystalline polymer polyimide induces formation polymer-COF junctions. These junctions are generated by threading chains through pores nanocrystals, thus allowing for spatial...
Abstract Electronic waste carries energetic costs and an environmental burden rivaling that of plastic due to the rarity toxicity heavy‐metal components. Recyclable conductive composites are introduced for printed circuits formulated with polycaprolactone (PCL), fillers, enzyme/protectant nanoclusters. Circuits can be flexibility (breaking strain ≈80%) conductivity (≈2.1 × 10 4 S m −1 ). These degraded at end life by immersion in warm water programmable latency. Approximately 94% functional...
Nanoconfinements are utilized to program how polymers entangle and disentangle as chain clusters engineer pseudo bonds with tunable strength, multivalency, directionality. When amorphous grafted nanoparticles that one magnitude larger in size than individual polymers, programming conformations can "synthesize" high-performance nanocomposites moduli of ≈25GPa a circular lifecycle without forming and/or breaking chemical bonds. These dissipate external stresses by disentangling stretching up...
Mechanical characteristics between spider and silkworm silks fibroins at nano scale are different owing to end serine residue in silkworm.
Currently available conductive inks present a challenge to achieving electrical performance without compromising mechanical properties, scalability, and processability. Here, we have developed blends of carbon black the commercially triblock copolymer (BCP), poly(styrene-ethylene-butylene-styrene)-g-maleic anhydride (SEBS-g-MAH) (FG1924G, Kraton), that can be readily applied as coating via spray-coating process, for wide range insulating materials (fabric, wood, glass, plastic). Simple but...
We applied a coarse-grained molecular dynamics simulation (CGMD) method and constructed elastic network model-based structures, actin cofilactin filaments. Based on normal mode analysis, the continuum beam theory was used to calculate mechanical properties results showed good agreement with established experimental data.
Understanding self‐assembling peptides becomes essential in nanotechnology, thereby providing a bottom‐up method for fabrication of nanostructures. Diphenylalanine constitutes an outstanding building block that can be assembled into various nanostructures, including two‐dimensional bilayers or nanotubes, exhibiting superb mechanical properties. It is known the effect ions critical conformational and chemical interactions membranes. In this study, we analyzed sodium chloride on...
We utilize nanoconfinements to program how polymers entangle and disentangle as chain clusters engineer pseudo bonds with tunable strength, multivalency, directionality. When amorphous are grafted nanoparticles that one magnitude larger in size than individual polymer, programming conformations can “synthesize” high performance nanocomposites moduli of ~25GPa a circular lifecycle without forming and/or breaking chemical bonds. These dissipate external stresses by disentangling stretching up...
