Preferably, the top coating layer includes a unit derived from -methacryloxypropylhepta(trifluoropropyl)-T8-silsesquioxane.

A flexible display device includes: a display panel to generate an image; and a window member on the display panel, the window member including: a base film; and a polymer layer including a first part and a plurality of second parts having lower hardness than that of the first part.

Provided is an electrically activated shape memory polymer composite capable of thermal shape reformation using electric power to heat the composite through its matrix glass transition temperature. The composite includes an adaptable polymer matrix component using a diglycidyl ether resin, at least one substantially well-dispersed conductive or magnetic nano-filler component, and at least one elastic, laminated layer. Also provided are methods of preparing the composite and methods of activating the composite. A shape reformation of the composite is triggered by applying an electric field at DC and/or at a frequency above about 1 Hz for a sufficient time.

The present invention relates to an exterior film of a building for protecting glass, which represents excellent weather resistance, impact resistance, and scratch resistance by a base layer combined with thermoplastic polyurethane and a functional coating layer, has self-healing ability, and can improve durability of glass by effectively blocking heat derived from ultraviolet and infrared rays.

The present disclosure describes a self-repairing article comprising an inflatable component comprising one or more material layers wherein at least one material layer comprises an elastomer. It also describes a self-repairing article comprising a sealed flexible package disposed within or between material layers of the inflatable component, and a repair composition disposed in the sealed flexible package, wherein the sealed flexible package comprises a metal foil and is configured to release the repair composition upon puncture of the inflatable component.

There are provided self sealing articles having a porous layer at least partially impregnated with a polymeric material where a first major surface of the porous layer is covered with the polymeric material and where the article passes Modified Test 1 of ASTM D-1970/D-1970M-13, Modified Test 2 of ASTM D-1970/D-1970M-13, or Modified Test 3 of ASTM D-1970/D-1970M-13 and is water vapor permeable and an air and water barrier. A self sealing article having a major surface of a porous layer that is coated with a polymeric material, where the porous layer comprises a microporous membrane, and where the article passes Modified Test 1 of ASTM D-1970/D-1970M-13, Modified Test 2 of ASTM D-1970/D-1970M-13, or Modified Test 3 of ASTM D-1970/D-1970M-13 and is water vapor permeable and an air and water barrier.

Provided are cementitious panel that include a swellable material within a core layer, a dense layer, and/or a sheet of facing material that make up a cementitious panel, as well as methods of manufacturing such cementitious panels that include a swellable material and methods of providing a moisture or water barrier in a cementitious panel.

A method and system for forming a self-sealing volume includes an elastomeric composite structure. The structure includes layers of a cast polyurethane derived from a neat polyurethane monomer reaction mixture that does not substantially react at room temperature. The polyurethane monomer reaction layer includes a reaction product of an organic polyisocyanate and a reactive hydrogen-containing material reacted with a mixture of a monomeric polyol and polymeric polyols. The structure may further include one or more layers of a fabric that have been precoated with an aliphatic polyurethane, and one or more sealing layers. A fuel impermeable inner liner may be positioned in an inner region. The sealing layers may comprise at least one of partially vulcanized natural rubber (NR), polyisoprene (IR), styrene butadiene (SBR), or a blend of SBR with NR or IR. A dimensionally correct, self-sealing volume may be created by inflating the volume during its cure.

A self-sealing bladder may automatically seal a puncture wound formed in a bladder wall thereof, such as due to being perforated by a projectile. Self-sealing bladders may be used in containers, such as fuel tanks, in order to prevent loss of fuel or other fluid from the container. Self-sealing bladders may contain a sealant material contained within one or more localized reservoirs formed within the bladder wall, the sealant material being pressurized within the bladder wall such that a localized reduction in pressure due to a perforation in the bladder wall causes the sealant material to migrate to the perforated site, whereupon the sealant material hardens, thereby sealing the wound. The localized reservoirs may include one or more channels and/or connecting layers extending therefrom and in fluid communication therewith, to facilitate migration of the sealant material away from the localized reservoirs and towards the perforated portion of the bladder wall.

In an embodiment, an aircraft includes a fuselage; a propulsion system powered by a fuel; and a fuel cell configured to store the fuel, the fuel cell including an inner layer configured to contact the fuel; an outer layer; and a self-sealing fabric structure formed from ultra-high molecular weight polyethylene (UHMWPE), the self-sealing fabric structure being between the inner layer and the outer layer, the self-sealing fabric structure being configured to self-seal a hole formed in the inner layer and the outer layer by a projectile.
