Title:
CONTROLLED MATERIAL INTERFACE TRANSFORMATION
Document Type and Number:
WIPO Patent Application WO/2014/018962
Kind Code:
A3
Abstract:
One aspect of the invention relates to materials and devices with interface layers with geometries which transform upon the direct or indirect application of load or displacement. The interface layers may transform from straight or flat shapes to wavy or hierarchically wavy morphologies or the waviness can be altered by load or displacement to tailor wavelength and amplitude of the interface geometry. Methods of predictably altering the interfacial morphology are also described. The ability to control material interface transformation can be used to regulate and to tune mechanical, chemical, thermal, swelling, photonic, phononic, electrical and optical functions, including color and reflectivity of the material.
