摘要:
Methods are provided for making reversible crosslinked polymers. Exemplary methods comprise reacting first and second thermoplastic polymers having non-hindered olefins in the presence of a metathesis catalyst under conditions sufficient to form a crosslinked polymer. In certain embodiments, the methods comprise providing a crosslink promoting additive to improve the strength of the crosslinked polymer. In some embodiments, the methods comprise decrosslinking a crosslinked polymer through a metathesis or an ozonolysis reaction.

Crosslinked flame retardant thermoplastic elastomer gels are provided. The crosslinked flame retardant thermoplastic elastomer gels comprise a char catalyst, a char former, a maleic anhydride-modified styrene ethylene/butylene styrene polymer, and a softener oil. Methods are provided of making crosslinked flame retardant thermoplastic elastomer gels.
摘要:
This invention relates to sol-gel methods for forming non-shrinking, high-glass composite materials and the products. Also taught is an inorganic-organic composite material having a solid interwoven network of an inorganic polymer matrix with interpenetrating polymerized alcohols. The inorganic matrix can be based on either Si or Ti atoms.

Methods are provided of making chemically crosslinked block copolymer gels and chemically crosslinked block copolymer gels. The methods include swelling an olefinic block copolymer having a functionalized soft block region and a functionalized hard block region, in a softener oil, and chemically crosslinking the olefinic block copolymer. Compositions are provided comprising a chemically crosslinked olefinic block copolymer having a functionalized hard block region and a functionalized soft block region and a softener oil.
摘要:
A sealing system for an acoustic touchscreen includes an elongate gel body between the touchscreen and the bezel of a housing onto which the touchscreen is mounted. The elongate gel body forms a seal around the perimeter of the touch-sensitive area of the touchscreen. A stop element controls and limits the amount of compression of the elongate gel body. The resulting seal is highly effective in protecting the unexposed parts of the touchscreen (i.e., areas other than the touch-sensitive area) from contaminants, especially liquid contaminants, at the cost of an acceptably low loss in acoustic signal strength.
摘要:
A carbon-based aerogel is disclosed in which the carbon atoms are arranged in a sheet-like nanostructure. The aerogel may be either a graphene oxide aerogel or a graphene aerogel and may further be reinforced with a polymer. A method for making the aerogel is also disclosed and includes providing graphite oxide, creating a dispersion of the graphite oxide in a liquid, and drying the dispersion to form a graphene oxide aerogel. In one embodiment, the graphene oxide aerogel is thermally treated to convert the graphene oxide to graphene.
