A polymer blend comprises PBI, PAEK, and PEI. A method of making the foregoing blend comprises the steps of intimately blending PBI, PAEK, and PEI by dissolving PBI, PAEK, and PEI in a strong acid or melt blending PBI, PAEK, and PEI.

Tri-blend resin of PBI, PAEK, and PEI

An ablative compound is made with a synthetic perovskite having an aspect ratio greater than 100.

Ablative compounds

A printed battery has a flexible backing sheet, a first conductive layer printed on said sheet; a first electrode printed on the first conductive layer; a second electrode layer printed on said first electrode layer; and a second conductive layer printed on said second electrode layer.

Printed battery

Battery separators made of a wettable, uniform mat of melt blown fibers. The melt blown fibers are thermally bonded to one another. These fibers are made of a thermoplastic material. The fibers have a diameter in the range of 0.1 to 13 microns (&#x3bc;) and lengths greater than 12 millimeters (mm). The mat has a basis weight ranging from 6 to 160 grams per square meter (g/m), a thickness of less than 75 microns (&#x3bc;), and an average pore size of 0.3 to 50 microns (&#x3bc;).

Melt blown battery separator

A fiber reinforced cementitious material and the fiber used therein are disclosed. The fiber reinforced cementitious material includes a conventional cementitious material and less than 5 pounds per cubic yard of the cementitious material of fibers dispersed therein. The fibers are made of a mixture of a thermoplastic polymer and an organometal compound wherein the metal of the compound is selected from the group consisting of Ti, Si, Zr, Al, and combinations thereof, and the organometal compound comprising less than 10% by weight of said fibers.

Fiber reinforced cementitious material

The present invention relates to a nonwoven substrate, and specifically to a nonwoven substrate imparted with a three-dimensional image, wherein the three-dimensional nonwoven substrate is particularly suited as a support substrate for a PCB (Printed Circuit Board) and similar application. By the utilization of a hydroentangled, three-dimensionally imaged support substrate impregnated with a durable resinous matrix, PCB's, and similar applications, can be imparted with unique and useful performance properties, to improve structural performance.

Three-dimensional nonwoven substrate for circuit board

A battery separator comprising at least one fibrous layer and at least one support layer, wherein the support layer is formed of an acid-resistant material and comprises a plurality of macroscopic openings.

Reinforced multilayer separator for lead-acid batteries

The invention concerns a battery separator comprising at least one first fibrous layer, at least one second fibrous layer, and at least one microporous polymer layer which is sandwiched between at least two fibrous layers, wherein the microporous polymer layer has an average pore size of less than 1 &mgr;m and wherein the at least one first fibrous layer has a thickness of at least 0.6 mm.

Multilayer separator for lead-acid batteries

Battery separators made of a wettable, uniform mat of melt blown fibers. The melt blown fibers are thermally bonded to one another. These fibers are made of a thermoplastic material. The fibers have a diameter in the range of 0.1 to 13 microns (&mgr;) and lengths greater than 12 millimeters (mm). The mat has a basis weight ranging from 6 to 160 grams per square meter (g/m ), a thickness of less than 75 microns (&mgr;), and an average pore size of 0.3 to 50 microns (&mgr;).

The invention concerns a battery separator comprising at least one microporous polymer layer and at least one fibrous layer, wherein the microporous polymer layer comprises micropores with an average pore size of less than 1 &mgr;m and a number of holes with a diameter which is greater than the average diameter of the pores of the fibrous layer.

Laminated multilayer separator for lead-acid batteries

A recombinant battery separator pad is made from a mat of meltblown ultrafine polymer fibers, with the fibers being treated with an agent to render them permanently wettable. The fibers include at least ten percent of less than one micron, with the majority less than five microns. The mat has a liquid porosity of at least 90% and a surface area of at least 1.0 m.sup.2 /g.

Recombinant battery separator

A method or removing and disposing hydrocarbons absorbed in a fabric, the method comprising the steps of providing a nonwoven fabric which comprises in excess of 55% fibers of polyvinyl alcohol, and wherein the nonwoven fabric is contaminated with hydrocarbons, disposing the nonwoven fabric in a warm aqueous bath heated to a temperature substantially less than the dissolution temperature of the polyvinyl alcohol fibers, whereby to cause liberation of the hydrocarbons from the fabric.

Method for removal of hydrocarbons from fabrics

A gel-type storage battery is made by preparing porous electrolyte pads having internal pockets containing a dry powdered gelling agent, and inserting the pad between adjacent battery electrodes before addition of acid. The gelling agent may include acid resistant superabsorbing polymer particles, which cause the pads to swell into intimate contact with the electrodes upon addition of the aqueous acid.
