| 20100018641 | Methods of Applying Skin Wellness Agents to a Nonwoven Web Through Electrospinning Nanofibers - Generally, the present invention is directed to, in one embodiment, a method for forming a composite nonwoven web configured to deliver skin wellness agents to the skin of a user. According to the method, an aqueous system of a hydrophilic polymer and a skin wellness agent is formed. The aqueous system is then electrospun onto a surface of a nonwoven web containing synthetic fibers. The resulting nanofibers have an average diameter of from about 50 nanometers to about 5000 nanometers, such as from about 200 nanometers to about 700 nanometers. | 01-28-2010 |
| 20100051188 | FLUOROPOLYMER CONTAINING LAMINATES - The multilayer film serves as a laminate. The film is a multilayered structure that, in its base form, encompasses an intermediate layer with first and second outer layer affixed to opposing sides of the intermediate layer. The first outer layer is a semi-crystalline fluoropolymer. The intermediate layer includes a polyester and the second outer layer is an olefinic polymer. The layers are bonded together in the noted order to provide the multilayer film. | 03-04-2010 |

| 20110174434 | Preparation of film coating of PLA biodegradable materials and its setup - A manufacturing method of coating film PLA biodegradable material and its setup using PLA biodegradable granule through drying machine to process water content before heating granule to molten on one hand and entering lamination head on the other hand through conveyer and squeezing out a thin film, then pushes lamination machine to fixed location and position lamination head between two rollers, than through lateral cylinder to control its displacement so that lamination head locates at center of two rollers, same time control rolling machine so that lamination point ascends to proper distance from outlet; while paper web or thin wood paper board surface heating through heater and enlarging pores, then using surface treatment so that pores are further enlarged to facilitate PLA thin film easy to coat film for providing fast lamination and increase yield and producing all kinds of paper containers and achieve natural degradation. | 07-21-2011 |
| 20110209820 | Piezoelectric composite nanofibers, nanotubes, nanojunctions and nanotrees - Piezoelectric nanostructures, including nanofibers, nanotubes, nanojunctions and nanotrees, may be made of piezoelectric materials alone, or as composites of piezoelectric materials and electrically-conductive materials. Homogeneous or composite nanofibers and nanotubes may be fabricated by electrospinning. Homogeneous or composite nanotubes, nanojunctions and nanotrees may be fabricated by template-assisted processes in which colloidal suspensions and/or modified sol-gels of the desired materials are deposited sequentially into the pores of a template. The electrospinning or template-assisted fabrication methods may employ a modified sol-gel process for obtaining a perovskite phase in the piezoelectric material at a low annealing temperature. | 09-01-2011 |

| 20140124131 | FABRICATION OF NANOPOROUS MEMBRANE - Various methods and systems are provided for fabrication of nanoporous membranes. In one embodiment, among others, a system includes electrode pairs including substantially parallel electrodes, a controllable power supply to control the electrical potential of each of the electrode pairs, and a syringe to eject an electrically charged solution from a needle to form a nanofiber. The orientation of the nanofiber in a nanofiber layer is determined by the electrical potentials of the electrode pairs. In another embodiment, a method includes providing a nanoporous membrane including nanofiber layers between a transferor and a mainmold of a stamp-through-mold (STM) where adjacent nanofiber layers are approximately aligned in different directions. A patterned membrane is sheared from the nanoporous membrane using the transferor and the mainmold of the STM and transferred to a substrate. | 05-08-2014 |
