Eliminating entanglements: A new strategy towards ultra-soft yet dry rubbe

See on Scoop.itBounded Rationality and Beyond

Medical implants mimic the softness of human tissue by mixing liquids such oil with long silicone polymers to create a squishy, wet gel. While implants have improved dramatically over the years, there is still a chance of the liquid leaking, which can be painful and sometimes dangerous.

 

Now, led by David A. Weitz, Mallinckrodt Professor of Physics and Applied Physics at Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and associate faculty member at the Wyss Institute for Biologically Inspired Engineering at Harvard, a team of polymer physicists and chemists has developed a way to create an ultra-soft dry silicone rubber. This new rubber features tunable softness to match a variety of biological tissues, opening new opportunities in biomedical research and engineering.

The material is featured on the cover of the journal Advanced Materials.
