Принадлежит: International Business Machines Corp

A flexible-to-rigid tube is flexible when routed and is then rigidized to increase burst strength. According to the preferred embodiments of the present invention, the flexible-to-rigid tube is included in a cooling plate assembly for transferring heat from electronic components mounted on a circuit board. In one embodiment, the flexible-to-rigid tube (while in a flexible state) includes a polydimethylsiloxane (PDMS) or other silicone containing pendant or terminal epoxy, vinyl and/or acrylate functional groups and an initiator (e.g., a sulfonium salt photoinitiator, a free radical photoinitiator, or a thermal initiator). In another embodiment, triallyl isocyanurate (TAIC) and an initiator are incorporated into a conventional PVC-based tubing material. The flexible-to-rigid tube changes from the flexible state to a rigid state via formation of a cross-linked network upon exposure to actinic radiation or heat.

The invention relates to methods for lowering the melt viscosity and thereby improving heat-sealability of a polyester. The invention also relates to a method for manufacturing a heat-sealed container or package from fibrous- based, polyester-coated packaging material, and a method for heat-sealing polyester. The solution according to the invention is subjecting polyester to electron beam (EB) radiation. The lowered melt viscosity allows a lower heat-sealing temperature, and permits sealing of polyester to an uncoated fibrous surface. The preferred polyester for the invention is polylactide, as such or as blended with another polyester.

A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy. The method also includes designing laser beam scan patterns that compensate for effects of multiphone absorption such as a shift in the depth of the laser pulse absorption location, and compensate for effects caused by high laser pulse energy such as thermal lensing. The method can be used to form a Fresnel lens in the optical zone. 14.-. (canceled)5.

A lead-acid battery separator with ultralow resistivity results from high porosity, controlled pore () size distribution, and an ionic surfactant () with a long alkyl side chain () that is anchored to the polymer matrix () of a silica-filled polyethylene separator. The surfactant cannot be easily removed or washed away and thereby imparts sustained wettability to the separator. Controlling the number of, and volume occupied by, the pores (i.e., porosity) and pore size distribution of the separator contributes to a reduction in electrical (ionic) resistivity. 1.

Method and apparatus for producing a nanocomposite material reinforced by unidirectionally oriented pre-dispersed alumina nanofibers

Номер: US20150031816A1
Автор: Ilya Grodnensky
Принадлежит: ANF Technology Ltd

Method for producing a nanocomposite material reinforced by unidirectionally oriented pre-dispersed alumina nanofibers. The process is suited for industrial-scale production of the nanocomposite materials. The nanocomposite production process involves, synthesis of unidirectionally oriented pre-dispersed alumina nanofibers, casting a mat of pre-dispersed nanofibers with a predetermined orientation in the atmosphere of air or other gas(es) by saturating the nanofibers with liquid polymer matrix. Polymer matrix may include thermosets or/and thermoplastics. The material forming the polymer matrix may be heated to its melting point temperature to transform it to liquid phase. After saturation, the polymer matrix is hardened by lowering its temperature or by means of exposing the polymer matrix to UV radiation, electron beam and/or chemical hardeners. The nanomaterial is composed of polymer composite with homogeneously dispersed uniformly oriented reinforcing nanofibers. Subsequently, the nanofibers in the nanocomposite are dispersed by means of subjecting to hydrodynamic stress, mechanical or/and ultrasound coarse dispersing.
