4D Printable Tough and Thermoresponsive Hydrogels

ACS Applied Materials & Interfaces, 2020
Hydrogels with attractive stimuli-responsive volume changing abilities are seeing emerging applications as soft actuators and robots. However, many hydrogels are intrinsically soft and fragile for tolerating mechanical damage in real world applications and could not deliver high actuation force because of the mechanical weakness of the porous polymer ...

Thermoresponsive poly(ionic liquid) hydrogels

Chemical Communications, 2013
A new series of LCST ILs have been copolymerised with crosslinkers of varying length to afford the first ever thermoresponsive poly(ionic liquid)-based hydrogels. These hydrogels exhibit surprisingly broad LCST and volume transition behaviour compared to standard thermoresponsive gels and linear ILs.

Elastin-Based Thermoresponsive Shape-Memory Hydrogels

Biomacromolecules, 2020
A shape-memory hydrogel is a programmable hydrogel material that can store specific shapes and execute functions in response to stimuli. In this report, we developed shape-memory hydrogels by creating double-network polymeric structures using a physically cross-linking elastin-like polypeptide (ELP) and a chemically cross-linking polyacrylamide (PAM ...

Multifunctional thermoresponsive designer peptide hydrogels

Acta Biomaterialia, 2017
We report the synthesis and characterization of multifunctional peptides comprised of a hydrogel forming β-sheet peptide segment and a matrix metalloproteinase 2 substrate containing a propargylglycinyl linker that is further derivatized with an RGD peptide sequence via "click" chemistry.

Rapid Photocrosslinkable Thermoresponsive Injectable Polyphosphazene Hydrogels

Macromolecular Rapid Communications, 2010
AbstractRapidly photocrosslinkable and thermosensitive polyphosphazene polymers have been prepared to overcome the limitations associated with long UV exposure. Short UV exposure on the thermosensitive gels under mild conditions leads to quick photocrosslinking of the acrylate groups in the polymer network, and results in a dual crosslinked network ...

Thermoresponsive Hydrogels for Cellular Delivery

Therapeutic Delivery, 2012
The delivery of living cells into a host body has emerged as a promising approach to treating a variety of different diseases and for tissue repair. However, one of the major obstacles for clinical success is to deliver the cells to the target tissue without losing control of cell fate and function after transplantation.

Thermoresponsive nanocomposite hydrogels with cell-releasing behavior

Biomaterials, 2008
Poly(N-isopropylacrylamide) (PNIPAAm) hydrogels become more hydrophobic when they reversibly switch from a water-swollen to a deswollen state above the volume phase transition temperature (VPTT, approximately 33 degrees C) which has been used to modulate cell adhesion.

Thermoresponsive chitosan–agarose hydrogel for skin regeneration

Carbohydrate Polymers, 2014
Healing enhancement and pain control are critical issues on wound management. So far, different wound dressings have been developed. Among them, hydrogels are the most applied. Herein, a thermoresponsive hydrogel was produced using chitosan (deacetylation degree 95%) and agarose.
