“…[114,115] The combination of UCST polymers and luminophores led to the development of luminescent thermometers and bio-imaging materials. [66,116,117] According to Jia et al, a UCST polymer with AIE function, PATC, was conjugated with a glucosaminemodified PAm, with specific recognition to bacteria such as Escherichia coli (Figure 7a). [118] The diblock copolymer could induce the aggregation of the bacteria at a temperature below UCST, and the bacteria aggregates were visualized due to the AIE-property, which facilitated targeted bactericidal action in vitro and in vivo under NIR radiation.…”

This review summarizes recent progress in the synergistic design strategy for thermoresponsive polymers possessing an upper critical solution temperature (UCST) in aqueous systems. To achieve precise control of the responsive behavior of the UCST polymers, their molecular design can benefit from a synergistic effect of hydrogen bonding with other interactions or modification of the chemical structures. The combination of UCST behavior with other stimuli‐responsive properties of the polymers may yield new functional materials with potential applications such as sensors, actuators, and controlled release devices. The advances in this area provide insight or inspiration into the understanding and design of functional UCST polymers for a wide range of applications.

“…[ 101 ] The second kind of thermoresponsiveness found in polymers is an upper critical solution temperature (UCST), [ 18 ] which can be explained by the Flory‐Huggins‐theory. [ 102 ] Below the UCST, polymer chains are collapsed due to preferred polymer–polymer interaction, while polymer–solvent interactions are preferred above the UCST. While enhanced solubility with increasing temperature is a common feature in most polymers, the effect is particularly pronounced in those with an UCST.…”

This review discusses the currently available 3D printing approaches, design concepts, and materials that are used to obtain programmable hydrogel actuators. These polymer materials can undergo complex, predetermined types of motion and thereby imitate adaptive natural actuators with anisotropic, hierarchical substructures. 3D printing techniques allow replicating these complex shapes with immense design flexibility. While 3D printing of thermoplastic polymers has become a mainstream technique in rapid prototyping, additive manufacturing of softer polymers including polymer hydrogels is still challenging. To avoid deliquescence of printed hydrogel structures, the polymer inks used for hydrogel manufacture need to be sheer-thinning and thixotropic, with fast recovery rates of the high viscosity state. This is achieved by adding polymer or particle-based viscosity modifiers. Further stabilization of the interfaces of the printed voxels, e.g., by UV cross-linking, is often also required to obtain materials with useful mechanical properties. Here state-of-the-art techniques used to 3D print stimulus responsive, programmable polymer hydrogels, and hydrogel actuators, as well as ink formulation and post-printing strategies used to obtain materials with structural integrity are reviewed.
