Non-covalent Interaction Cooperatively Induced Stretchy, Tough and Stimuli-Responsive Polyurethane-Urea Supramolecular (PUUS) Hydrogels
Up to now, fabrication of strong and stimuli-responsive supramolecular hydrogels via an easy molecular design and synthesis procedure is still a big challenge. In this work, a series of hydrophobically modified linear polyurethane–urea copolymers and one polyurethane copolymer were prepared via a greatly simplified one-pot approach to investigate the synergistic effect between hydr...

Mechanically strong and stretchable polyurethane–urea supramolecular hydrogel using water as an additional in situ chain extender
Mechanically strong hydrogels have attracted much interest as a result of their potential applications as biomaterials. However, it is still a challenge to produce mechanically strong supramolecular hydrogels because of the inherently weak characteristics of non-covalent interactions. A novel polyurethane–urea supramolecular hydrogel with excellent mechanical properties was develop...

Mechanically strong and stretchable PEG-based supramolecular hydrogel with water-responsive shape-memory property
A strong and highly stretchable supramolecular hydrogel with a shear modulus of 200 kPa, an elongation at break of 770% at 4 MPa stress and a water-responsive shape-memory property is developed. The whole shape-memory procedure including shape deformation, fixing
and recovery can be realized under mild and green conditions, i.e. in air and water.

Core-Shell Capsules Based on Supramolecular Hydrogels Show Shell-Related Erosion and Release Due to Confinement
Hydrogel-containing core–shell capsules are useful as drug delivery vehicles for many
biomedical applications, especially when release of incorporated guests can be controlled.
Here, we developed a one-step organic solvent-free method to prepare such core–shell
capsules using a synthetic and a natural supramolecular hydrogel, for the core and shell, respectively. A solution containing ...

[Chem. Commun] Reversible morphology transitions of supramolecular polymer self-assemblies for switch-controlled drug release
A novel method for switch-controlled drug release was developed through the reversible morphology transitions of supramolecular branched copolymer self-assemblies. The reversible transitions from vesicles to nanoparticles were successfully achieved by alternating UV and visible light irradiation to obtain morphology-controlled drug release in a switch mode.
In this st...

Amphiphilic star-block copolymers based on a hyperbranched core: Synthesis and supramolecular self-assembly
Novel amphiphilic star-block copolymers, star poly(caprolactone)-block-poly[(2-dimethylamino)ethyl methacrylate] and poly(caprolactone)-block-poly(methacrylic acid), with hyperbranched poly(2-hydroxyethyl methacrylate) (PHEMA–OH) as a core moiety were synthesized and characterized. The star-block copolymers were prepared by a combination of ring-opening polymerization and atom transfer radical po...

Synthesis and Supramolecular Self-Assembly of Thermosensitive Amphiphilic Star Copolymers Based on a Hyperbranched Polyether Core
A novel amphiphilic thermosensitive star copolymer with a hydrophobic
hyperbranched poly (3-ethyl-3-(hydroxymethyl)oxetane) (HBPO) core and
many hydrophilic poly(2-(dimethylamino) ethyl methacrylate) (PDMAEMA)
arms was synthesized and used as the precursor for the aqueous solution
self-assembly. All the copolymers directly aggregated into core–shell
unimolecular micelles (around 10 nm) and s...

Supramolecular self-assembly of amphiphilic hyperbranched polymers at all scales and dimensions: progress, characteristics and perspectives
This feature article describes the supramolecular self-assembly of hyperbranched polymers
(HBPs), including the progress, unique characteristics and future
perspectives. HBPs are irregular in molecular structure compared with
that of linear block copolymers and dendrimers. However, similar to these well-defined polymer tectons, HBPs have displayed great potential to be excellent precursor...
