In Physics Today: Patterning 2D Growth to Make 3D Objects

Publication date: Thu, May 17, 2012 - 5:22pm
A story in Physics Today highlights the work of UMass postdoc James Hanna and Professor Christian Santangelo. Along with colleagues in the Polymer Science Department, they have developed a method to program 2D polymer films to buckle into nearly arbitrary 3D shapes. A polymer film is patterned with an array of dots whose size determines the degree a region of the gel will swell in response to a temperature change. Their research appears in the March 9th issue of Science magazine and is featured in a Perspective. ...more
