A manufacturing method of a heat insulating sheet of the present disclosure includes a composite generating step of impregnating a nonwoven fiber with a basic sol prepared to generate a composite of a hydrogel-nonwoven fiber, the basic sol being prepared by adding carbonate ester to a water glass composition; and a drying step of drying a liquid contained in the composite at a temperature lower than a critical temperature of the liquid and a pressure lower than a critical pressure of the liquid to remove the liquid from the composite. A heat insulating sheet according to the present disclosure includes an aerogel and a nonwoven fiber, and has a compression rate at 0.30 MPa to 5.0 MPa of 40% or less. In an electronic device of the present disclosure, the heat insulating sheet is disposed between an electronic component and a housing. In a battery unit of the present disclosure, the heat insulating sheet is disposed between batteries. This provides a heat insulating sheet that can be used under a high load and a manufacturing method thereof, and an electronic device and a battery unit including the same.

The present invention provides a method of manufacturing a highly functional surface-modified fibrous material with high added value, to which a novel functionality is imparted while making use of the characteristics inherent in the fibrous material, by modifying the surface of a natural fibrous material derived from an animal or a plant, or of a synthetic fiber; and a surface-modified fibrous material thereby obtained. The method of manufacturing a surface-modified fibrous material according to the invention includes attaching an inorganic material on the surface of a fibrous material by a sol-gel reaction, while allowing the fibrous material to move via an air stream. Preferably, an atmospheric-pressure low-temperature plasma is further applied to the surface of the fibrous material on the surface of which the inorganic material has been attached, while allowing the fibrous material to move via an air stream.

A detergent composition containing water, a component (A) which is a silica capsule enclosing a functional agent, and a component (B) which is a cationic polymer having a weight average molecular weight of 500,000 or more and 5,000,000 or less and obtained by polymerizing an unsaturated monomer having a cation group (excluding those enclosed in the silica capsule of the component (A)).

Gel-wipes suitable for use in personal care and household cleansing applications are disclosed, which include a substrate having a first surface, a second surface opposing the first surface and a body disposed between and defined by the first and second surfaces, fibers having an outer surface and an inner core, a polymeric gel distributed throughout the substrate such that a substantial portion of the fibers contain the polymeric gel distributed throughout the inner core of the fibers; and a liquid cleansing composition, wherein the inner core of a substantial portion of the fibers and the polymeric gel are substantially free of the liquid cleansing composition; as well as methods of making the gel-wipe.

A fabricating method of a non-woven film, for electronic components, includes the following steps. Providing a polyetherimide substrate and an aerogel dispersion, in which the aerogel dispersion includes an aerogel, and the aerogel has a moisture content between 0.7% and 0.9% and a porosity between 85% and 95%. Dipping the polyetherimine substrate in the aerogel dispersion, such that the aerogel dispersion covers the polyetherimine substrate. Performing a thermal compression process on the polyetherimide substrate, such that the aerogel and the polyetherimide substrate are composited with each other. Performing an ultrasonic oscillating process on the polyetherimine substrate, such that the aerogel not being composited with the polyetherimine substrate is removed.

An aerogel composite has excellent thermal stability and flame retardancy even when exposed to a high-temperature environment for a long period of time.

Porphyrin-modified antimicrobial peptides as described here may be used as indicators of the presence of microbial targets. Their application may be as (for example) (1) fluorescent indicators in a microarray format, (2) fluorescence or absorbance based indicators in traditional solution based applications, or (3) reflectance based indicators for use in reagent-less detection platforms.

A thread intended to be woven. The thread includes a core made of a polymer, and a sheath covering the core. The sheath is formed of polyvinyl chloride (PVC). The thread individually presents, at 130 C., an elongation at maximal force, such as measured with the D411099 standard, greater than or equal to 20%.
