Polymers and soft materials news

Inspired by animal chirps, engineers have devised a faster and more accurate rheological technique for measuring the properties of soft materials.

Scientists have used magnetic fields to create liquid crystal elastomers that can move in any direction in response to multiple types of stimuli.

Scientists have developed a liquid crystal elastomer with auxetic properties, meaning it gets thicker when stretched.

Echolocation for soft materials

A new 3D bioprinting technique that works with natural materials can produce lifelike organ tissue models for study or drug screening.

A novel biodegradable polymer that incorporates citrate can provide the extra energy that stem cells need to form new bone tissue.

A novel hydrogel that naturally adheres to soft tissue like cartilage and the meniscus can withstand mechanical stresses and extensive deformation.

A 3D printing technique can produce intricate structures from a novel, stiff material made from seaweed-derived alginate and graphene oxide.

A macroporous hydrogel made by combining gelatin microgels with an enzyme can allow the passage of cells through it to aid wound healing.

Liquid crystals can template the formation of arrays of polymer nanofibers to produce coatings that are sticky, repellent, insulating or light emitting.

By combining epoxy with graphene foam, scientists have produced a stiff, conductive composite material for electronic applications.
