| 20110175259 | Method of Orientating Fillers in Composite Materials - A method is provided of fabricating a composite incorporating fillers. The method includes the steps of depositing the fillers in a matrix material either in a rapid prototyping device or prior to inserting the matrix material into a mold. The mold is positioned at a desired location with respect to an electrical field such that at least a portion of the fillers in the matrix material align in a first direction in response thereto. For producing a heterogeneous composite through a rapid prototyping process, the electrodes are positioned at a desired orientation to align the fillers. Thereafter, at least a portion of the matrix material is cured with desirable filler orientation. The procedure is repeated with the desired filler orientation and distribution being introduced layer by layer within the composite. | 07-21-2011 |
| 20120068383 | MATERIAL FABRICATION USING ACOUSTIC RADIATION FORCES - Apparatus and methods for using acoustic radiation forces to order particles suspended in a host liquid are described. The particles may range in size from nanometers to millimeters, and may have any shape. The suspension is placed in an acoustic resonator cavity, and acoustical energy is supplied thereto using acoustic transducers. The resulting pattern may be fixed by using a solidifiable host liquid, forming thereby a solid material. Patterns may be quickly generated; typical times ranging from a few seconds to a few minutes. In a one-dimensional arrangement, parallel layers of particles are formed. With two and three dimensional transducer arrangements, more complex particle configurations are possible since different standing-wave patterns may be generated in the resonator. Fabrication of periodic structures, such as metamaterials, having periods tunable by varying the frequency of the acoustic waves, on surfaces or in bulk volume using acoustic radiation forces, provides great flexibility in the creation of new materials. Periodicities may range from millimeters to sub-micron distances, covering a large portion of the range for optical and acoustical metamaterials. | 03-22-2012 |
| 20120299221 | MAGNETIC REVERSIBLY ATTACHED TEMPLATE (MRAT) AND USES THEREFOR - The magnetic reversibly attached template (MRAT) are solid devices made of biocompatible material containing a magnetic material. These devices can be made in any shape using microfabrication, milling, and molding and can be positioned and secured using magnetic forces. The applications of the M RAT encompass the patterning of biological and non-biological materials including cells, nucleic acids, peptides, proteins, aqueous solutions, polymers, rubbers, and other reagents on solid surfaces. | 11-29-2012 |

| 20160089842 | CONTINUOUS ROLL-TO-ROLL PROCESS DESIGN FOR VERTICAL ALIGNMENT OF PARTICLES USING ELECTRIC FIELD - A method of preparing an anisotropic polymer film using an electric field generator. The method of preparing an electric field generator comprising supplying an electric field across an electric field application zone, where the electric field is generated by a first electrode having a first charge and a second electrode having a charge opposite of the first, passing a polymer film that optionally includes dispersed particles through the electric field application zone, where the polymer film contacts the first electrode to induce orientation, and freezing the polymer film to lock the orientation before the polymer film exits the electric field application zone. | 03-31-2016 |

| 20100193999 | ELECTROSPINNING OF PTFE WITH HIGH VISCOSITY MATERIALS - An improved process for forming a PTFE mat is described. The process includes providing a dispersion with PTFE, a fiberizing polymer and a solvent wherein said dispersion has a viscosity of at least 50,000 cP. An apparatus is provided which comprises a charge source and a target a distance from the charge source. A voltage source is provided which creates a first charge at the charge source and an opposing charge at the target. The dispersion is electrostatically charged by contact with the charge source. The electrostatically charged dispersion is collected on the target to form a mat precursor which is heated to remove the solvent and the fiberizing polymer thereby forming the PTFE mat. | 08-05-2010 |
