Fully plastic actuator through layer-by-layer casting with ionic-liquid-based bucky gel.
This work reports the first dry actuator that can be fabricated simply through layer-by-layer casting with “bucky gel”, a breakthrough in the design of miniaturized mechanical devices.
Stretchable active-matrix organic light-emitting diode display using printable elastic conductors.
The manufacture of printable elastic conductors comprising single-walled carbon nanotubes (SWNTs) uniformly dispersed in a fluorinated rubber is described, which is constructed a rubber-like stretchable active-matrix display comprising integrated printed elastic conductor, organic transistors and organic light-emitting diodes.
Molecular Ordering of Organic Molten Salts Triggered by Single-Walled Carbon Nanotubes
The use of a polymerizable ionic liquid as the gelling medium allows for the fabrication of a highly electroconductive polymer/nanotube composite material, which showed a substantial enhancement in dynamic hardness.
High-water-content mouldable hydrogels by mixing clay and a dendritic molecular binder
It is reported that water and clay, when mixed with a very small proportion of organic components, quickly form a transparent hydrogel, which can be moulded into shape-persistent, free-standing objects owing to its exceptionally great mechanical strength, and rapidly and completely self-heals when damaged.

It is found that the SWNT content can be increased up to 20 weight percent without reducing the mechanical flexibility or softness of the copolymer, and the elastic conductor allows for the construction of electronic integrated circuits, which can be mounted anywhere, including arbitrary curved surfaces and movable parts, such as the joints of a robot's arm.
High performance fully plastic actuator based on ionic-liquid-based bucky gel
Functional Supramolecular Polymers
The specific features of supramolecular polymers that can lead to applications in a variety of fields are reviewed, including: materials—in which processability and self-healing properties are of interest; biomedicine— in which the concerns are dynamic functionality and biodegradability; and hierarchical assembly and electronic systems—with an interest in unidirectionality of charge flow.
Light-harvesting ionic dendrimer porphyrins as new photosensitizers for photodynamic therapy.
Both dendrimer porphyrins with either 32 quaternary ammonium groups or 32 carboxylic groups had far lower dark toxicity as compared with PIX, demonstrating their highly selective photosensitizing effect in combination with a reduced systemic toxicity.
