Composites comprising polymeric nanofibers, metal oxide nanoparticles, and optional surface-segregating surfactants and precursor compositions are disclosed. Also disclosed are nonwoven mats formed from the composites and methods of making and using the composites. The composites enable the deployment of nanostructured materials for water treatment within a self-contained membrane with high water fluxes, as well as a number uses.

A sand additive for use in a “no bake” foundry mix composition having a polyurethane-based binder system reduces the amount of smoke emitted when molds and cores formed from the composition are exposed to molten metal, as compared to when the sand additive is not used. The sand additive comprises yellow iron oxide having the chemical formula Fe(OH).sub.3. It can also comprise at least one of red iron oxide, black iron oxide and wüstite. In such cases, the yellow iron oxide accounts for about 10 to about 40 weight percent of the combined weight of the yellow iron oxide, red iron oxide, black iron oxide and wüstite, and preferably, about 20 to about 30 weight percent of the combined weight of the yellow iron oxide, red iron oxide, black iron oxide and wüstite.

A glove of a form typically, although not necessarily exclusively, provided for single or limited use purposes and discarded thereafter. The glove is to prevent contact between a product and a person's hand and to avoid contamination. The glove material includes components capable of detection by at least one form of noncontact detection apparatus which renders the glove or portion detectable if discarded and inadvertently becomes part of a manufacturing process or product. The components render the glove detectable by using metal detection apparatus and/or X-ray detection apparatus which may allow removal of the glove. The glove may also include an antimicrobial agent as part to prevent or reduced contamination on the surface of the glove. The glove can also be rendered biodegradable.

Provided is a maleimide resin film highly filled with inorganic particles and having a superior adhesion force. The maleimide resin film contains: (a) a maleimide represented by the following formula (1):

##STR00001## wherein A independently represents a tetravalent organic group having a cyclic structure(s); B independently represents an alkylene group that has not less than 6 carbon atoms and at least one aliphatic ring having not less than 5 carbon atoms, and may contain a hetero atom; Q independently represents an arylene group that has not less than 6 carbon atoms, and may contain a hetero atom; W represents a group represented by B or Q; n represents a number of 0 to 100, m represents a number of 0 to 100, provided that at least one of n or m is a positive number; (b) a (meth)acrylate; (c) inorganic particles; and (d) a curing catalyst.

A method for manufacturing an organism adhesion reduction paint includes a first process of gelling a raw material composition that includes polyvinyl alcohol and at least one of a hydroxyl group-containing inorganic compound or an inorganic oxide; a second process of drying and subsequently pulverizing a resulting product in the first process to thereby obtain a composite gel fine powder; and a third process of adding the composite gel fine powder to a main component of a two-component urethane paint and stirring, to thereby prepare a main component of the organism adhesion reduction paint, and also adding a curing agent immediately before use.

Examples of the present disclosure provide fluoropolymers and methods for forming and using such fluoropolymers. Fluoropolymers include polyfluorobenzoxazines and polyfluoroimides. Methods for forming polyphthalonitriles are also provided. The present disclosure is further directed to compositions containing one or more fluoropolymers and one or more metal oxides.

Provided are a nanoparticle-polymer fluorescent composite and a method of preparing the same. The method includes preparing magnetite (Fe.sub.3O.sub.4) nanoparticles, mixing the magnetite (Fe.sub.3O.sub.4) nanoparticles, an organic polymer having an aliphatic carbon chain, and a solvent for dissolving the organic polymer to prepare a preliminary composite and drying the preliminary composite to form a nanoparticle polymer composite, and irradiating a pulse laser to the nanoparticle polymer composite to change the magnetite (Fe.sub.3O.sub.4) nanoparticles to Wustite nanoparticles and providing conjugated polymer characteristics to the organic polymer.

A cellulose nanofiber-supporting inorganic powder includes a cellulose nanofiber and an inorganic powder, wherein the cellulose nanofiber is supported on the inorganic powder. Thus, the cellulose nanofiber may be readily and uniformly dispersed in a resin or rubber composition, and, by adding to the composition, a cellulose nanofiber-supporting inorganic powder is capable of improving the physical properties of a resin or a rubber.

The present disclosure is drawn inkjet inks, which can include an aqueous ink vehicle and a pigment particle having a block copolymer attached to a surface of the pigment particle. The block copolymer can be linked to the surface through a nitrogen atom-containing coupling group bonded to the surface through the nitrogen atom. The block copolymer can include a steric stabilizing block formed by polymerizing a monomer having a sterically bulky group, and an ionic stabilizing block formed by polymerizing a monomer having an acidic group or a basic group.
