But by modifying the underlying network of cellulose fibers, etching off surface \u201cfluff\u201d and applying a thin chemical coating, researchers have created a new type of paper that repels a wide variety of liquids \u2013 including water and oil.\u003C\/p\u003E\u003Cp\u003EThe paper takes advantage of the so-called \u0022lotus effect\u0022 \u2013 used by leaves of the lotus plant \u2013 to repel liquids through the creation of surface patterns at two different size scales and the application of a chemical coating. The material, developed at the Georgia Institute of Technology, uses nanometer- and micron-scale structures, plus a surface fluorocarbon, to turn old-fashioned paper into an advanced material.\u003C\/p\u003E\u003Cp\u003EThe modified paper could be used as the foundation for a new generation of inexpensive biomedical diagnostics in which liquid samples would flow along patterns printed on the paper using special hydrophobic ink and an ordinary desktop printer. This paper could also provide an improved packaging material that would be less expensive than other oil- and water-repelling materials, while being both recyclable and sustainable.\u003C\/p\u003E\u003Cp\u003E\u201cPaper is a very heterogeneous material composed of fibers with different sizes, different lengths and a non-circular cross-section,\u201d said\u0026nbsp;\u003Ca href=\u0022http:\/\/www.chbe.gatech.edu\/faculty\/hess\u0022\u003EDennis Hess\u003C\/a\u003E, a professor in the Georgia Tech\u0026nbsp;\u003Ca href=\u0022http:\/\/www.chbe.gatech.edu\/\u0022\u003ESchool of Chemical and Biomolecular Engineering\u003C\/a\u003E. \u201cWe believe this is the first time that a superamphiphobic surface \u2013 one that repels all fluids \u2013 has been created on a flexible, traditional and heterogeneous material like paper.\u201d\u003C\/p\u003E\u003Cp\u003EResearch leading to development of the superamphiphobic paper has been supported by the Institute for Paper Science and Technology (IPST) at Georgia Tech.
