GE creates super-repellent plastic Science/Biology
You know how annoying it is to get those last few drops of ketchup out of the bottle? Well, GE has solved your problems. They have created a super-repellent plastic which is superhydrophobic, meaning it greatly repels anything water-based. That means even substances like honey will easily slide out of a container made of the material. The biggest difference between this and similar materials like Teflon? Cost.
While several existing engineered materials behave this way, the GE accomplishment is noteworthy because it was done with an inexpensive plastic, GE's Lexan, that's normally "hydrophilic," meaning water spreads out on contact, not something that's "hydrophobic" to start with, such as Teflon or silicone-based materials. These latter materials are far more expensive compared with Lexan, a ubiquitous thermoplastic used in products ranging from CDs and DVDs to automotive headlamps, food storage containers, and common household appliances.

While GE is not predicting specific applications yet, a few are theoretically possible. A cheap superhydrophobic plastic could be used in food containers from which every last bit of ketchup or syrup would flow right out. It could also allow for a building panel that repels water so efficiently that rain would wash away dirt -- making it essentially self-cleaning.

Such a material could be a bonanza for medicine, too. In the field of microfluidics, superhydrophobic materials are needed so that tiny volumes of blood or other body fluids can flow more easily through micrometer-scale channels. Although some superhydrophobic materials are currently available, they're expensive enough to preclude visions of diagnostic gadgets that you could buy in a drugstore. A cheap plastic, though, could make such a disposable diagnostic chip feasible. "It is a big deal and it is important for the microfluidics applications," says Neelesh Patankar, a mechanical engineer and microfluidics at Northwestern University.
Cheap and convenient - sounds pretty fantastic.
