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...
Commercial adhesives are petroleum-based thermoset networks or nonbiodegradable thermoplastic hot melts, making them ideal targets for replacement by biodegradable alternatives. Poly(3-hydroxybutyrate) (P3HB) is a biorenewable and alternative to conventional plastics, but microbial P3HB, which has stereoperfect stereomicrostructure, exhibits no adhesion. In this study, elucidating the fundamental relationship between chemocatalytically engineered P3HB stereomicrostructures adhesion...
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...
The ability to directly modify the topology of a surface with three-dimensional micron-scale features provides both mechanism controlling how it interacts surrounding environment and potential impart functional features. Using direct material jetting based additive manufacturing technologies, we report printing microstructures onto aluminium coupons previously finished polyurethane (PU) coatings where overcoat window proved crucial for this process. effect PU coating's age on development...
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...
