1. Nanotechnology & Tennis Balls By Kolby Wagner Kolby Wagner Shawn Shroyer Shawn Shroyer

2. Longer lasting balls  Air D-Fense Barrier Coatings in Wilson Racquet Sports DoubleCore premium ball  Inner core of this ball is coated with Air D-Fense barrier to maintain the air pressure  Bounce at least two times longer, increasing the playable time of the ball

3. How it works  Exfoliated clay is added to a liquid polymer that lines the inside of the ball  The clay plates overlap each other in a parallel manner  Since the plates over lap each other the air must travel through many layers to escape the inside bladder  Therefore the air stays inside the ball better

4. Why it’s nano  The nano coating is a second core on the inside of the tennis ball that is sprayed or rolled onto the rubber  It is made up of overlapping exfoliated clay plates  These plates are approximately 1 nanometer thick

5. Benefits of the ball  They do not fuzz up quickly  Most balls last a set and a half  Wilson’s Double Core balls will last 3 sets  Environmental Considerations
