Nanotech breakthrough promises stronger condoms and golf balls

Scientists at the University of Queensland have developed a new polyurethane coating with potential applications for improving the strength and flexibility of anything from condoms and golf balls to shoe soles and Lycra.

Dr Darren Martin, a materials scientist with UQ's Australian Institute for Bioengineering and Nanotechnology explains that the new technology is the result of seven years work at the University of Queensland and which is already garnering significant interest in an industry worth several billions of dollars.

Distinguishing the work of Dr Martin and his team from other similar ideas is its use of much smaller plates in polyurethane mixtures. The scientists are now awaiting receipt of a worldwide patent.

Martin had initially been searching for ways to keep his golf balls from falling apart after only a few games. What he came up with was a type of synthetic nanoparticle, or nanoscale disc-like particles, that can be added to conventional thermoplastic polyurethane (TPU) to extend its benefits and performance. TPUs are widely used in a range of sporting equipment and textiles.

“I'm a single-figure golfer and I was getting frustrated with paying a lot of money for balls that only end up getting damaged after a few holes,” Dr Martin said.

Multinational manufacturers including Dow, BASF and Bayer have already expressed interest. The team is now in talks with a golf ball manufacturer, while exploring a wide array of other potential applications. Clearly the condom is a natural fit.

“We could make softer and thinner condoms that allow greater sensitivity and are actually stronger than current ones, while also reducing the risk of allergic response which some people have to latex rubber,” Dr Martin said. “We can all see the advantages of that application.” CONTINUED
