Tuning Dry and Wet Adhesion with a Branched Supramolecular Polymer Solution [PDF]

open access: yesSmall Science, 2023
Endowing adhesives with both dry and wet adhesion to surfaces from hard substrates to soft biological tissues is challenging. Herein, a branched supramolecular polymer is introduced in dry‐ and wet‐crosslinking forms to adaptively achieve dry and wet ...

Influences of Reservoir Conditions on the Performance of Cellulose Nanofiber/Laponite-Reinforced Supramolecular Polymer Gel-Based Lost Circulation Materials [PDF]

open access: yesGels
Lost circulation during drilling has significantly hindered the safe and efficient development of oil and gas resources. Supramolecular polymer gel–based lost circulation materials have shown significant potential for application due to their unique ...

Highly robust supramolecular polymer networks crosslinked by a tiny amount of metallacycles [PDF]

open access: yesNature Communications
Supramolecular polymeric materials have exhibited attractive features such as self-healing, reversibility, and stimuli-responsiveness. However, on account of the weak bonding nature of most noncovalent interactions, it remains a great challenge to ...

Mechanically robust supramolecular polymer co-assemblies [PDF]

open access: yesNature Communications, 2022
Reversible assembly of supramolecular polymers renders these materials with healing and recycling properties but mechanical properties are often inferior to those of conventional plastics.

Preparation and Performance Evaluation of a Supramolecular Polymer Gel-Based Temporary Plugging Agent for Heavy Oil Reservoir [PDF]

open access: yesGels
When encountering heavy oil reservoirs during drilling, due to the change in pressure difference inside the well, heavy oil will invade the drilling fluid, and drilling fluid will spill into the reservoir along the formation fractures, affecting the ...

Nested non-covalent interactions expand the functions of supramolecular polymer networks [PDF]

open access: yesNature Communications
Supramolecular polymer networks contain non-covalent cross-links that enable access to broadly tunable mechanical properties and stimuli-responsive behaviors; the incorporation of multiple unique non-covalent cross-links within such materials further ...

Non-trivial stimuli-responsive collective behaviours emerging from microscopic dynamic complexity in supramolecular polymer systems [PDF]

open access: yesNature Communications
Supramolecular polymers are composed of monomers that self-assemble non-covalently generating distributions of fibres in continuous exchange-and-communication with each other and the surroundings.

Multistep sequence-controlled supramolecular polymerization by the combination of multiple self-assembly motifs

open access: yesiScience, 2023
Summary: The precise sequence control of polymer chain is an important research topic of polymer chemistry. Although some methods such as iterative synthesis and supramolecular polymerization have been developed to fabricate sequence-controllable polymer,

Thermo-responsive chiral micelles as recyclable organocatalyst for asymmetric Rauhut-Currier reaction in water

open access: yesNature Communications, 2023
Developing eco-friendly chiral organocatalysts with the combined advantages of homogeneous catalysis and heterogeneous processes is greatly desired. In this work, a family of amphiphilic one-handed helical polyisocyanides bearing phosphine pendants is ...
