Polymer

Although it is possible to recycle Plexiglass, it's a complex and inefficient process, so it generally just isn't done. A simple new technique, however, is claimed to break the plastic down into all of its building blocks for near-complete recycling.

Geckos are able to maintain a grip on wet surfaces not because their toe pads repel water, but because they attract it. A new polymer, which was inspired by this phenomenon, could find use in shoe soles that keep people from slipping on ice.

In what they're calling the "highest density of mechanical bonds ever achieved," researchers created a super-strong flexible material that works very much like chainmail. The breakthrough has already demonstrated its ability to improve body armor.

Gels and glasses are on opposite ends of the material spectrum, but engineers at North Carolina State University (NCSU) have developed a new class called “glassy gels” that are both strong and flexible, as well as sticky and self-healing.

Concrete may seem strong, but it can be surprisingly vulnerable to the elements. Now researchers at Drexel University have demonstrated a type of self-healing concrete embedded with “BioFibers” that use bacteria to patch up cracks as they form.

3D printing single objects out of different materials can be difficult, if those materials cure at different rates. The new Inkbit system addresses that problem, and has been used to print a complex functional robotic hand… in just one print job.

Researchers have created a molecule that, when added to polymers, increases the material’s durability by making it more able to withstand temperature fluctuations. They say it could be used in everything from plastic phone cases to missiles.

Most three-dimensional glass objects are produced via either a molding, blowing or 3D-printing process. Chinese scientists, however, have devised a technique of folding such items into shape – and it has some key advantages over other methods.

A versatile new material helps in the ongoing battle against corrosion. The polymer coating not only protects against corrosion, but highlights cracks as they form, automatically repairs damage to itself, and can be recycled at the end of its life.

A team of researchers has developed a new material that’s not only elastic, but is impervious to gases and liquids – something this kind of material is usually bad at. The material could be useful for making flexible batteries or wearable electronics.

3D printing technology is used not only to build things as large as houses, but also as small as snowflakes. A new material allows the latter to be much stronger than ever before, and to be printed considerably faster.

Plastics can be hard, plastics can be soft, but can plastics be both at the same time? Scientists have been exploring this question and produced a first-of-a-kind material that is pliable in some sections and stiff in others.
