Synopsis: Materials: Classes of materials: Polymers: Polycarbonate:

the films still consist of polycarbonate also made or of polyethylene terephthalate (PET). In order to create the miniature plastic channels that define the shape,

At the crown of the helmet a flexible panel that has a polycarbonate shell attaches with a living hinge.

Polycarbonate skeleton of robot, testing apparatus, fully blown membrane (last two pix. click on image to enlarge) This ground-breaking research was published in Bioinspiration

The end result is a polycarbonate 3d printed streamlined skeleton which had no moving parts (Fig. 1) and no energy storage device other than a thin elastic outer membrane.

when scientists discovered that it could be used to make polycarbonate plastic--a hard, durable, and transparent material perfect for everything from water bottles to medical devices.

In the journal Angewandte Chemie("Construction of Versatile and Functional Nanostructures Derived from CO2-based Polycarbonates),

one-pot conversion of CO2 and epoxides to polycarbonate block copolymers that contain both water-soluble and hydrophobic regions

Versatile nanostructures made from CO2 based polycarbonates. Wiley-VCH) CO2 and epoxides (highly reactive compounds with a three-membered ring made of two carbon atoms

and one oxygen atom) can be polymerized to form polycarbonates in reactions that use special catalysts.

However, because current CO2-based polycarbonates are hydrophobic and have no functional groups, their applications are limited.

In particular, biomedical applications, an area where the use of biocompatible polycarbonates is established well, have been left out.

the researchers have been able to produce amphiphilic polycarbonate block copolymers in which both the hydrophilic and hydrophobic regions are based on CO2.

Because it is very difficult to find building blocks to make hydrophilic polycarbonates, the researchers used a trick:

The AGE-containing polymer grows on both ends of the existing polycarbonate, leading to a triblock copolymer.

Some of the amphiphilic polycarbonates made by this method are able to aggregate into particles or micelles in a self-organization process.

The glasses are made from impact-resistant polycarbonate with a scratch-resistant lens that also reduces glare to the eyes.
