A polymer composite material includes a blend of one or more thermoplastic polymers and one or more bio-based flame retardant additives, wherein the one or more bio-based flame retardant additives are present in an amount of 35 to 100 parts per 100 parts by weight of the one or more thermo-plastic polymers. A method of forming the polymer composite material includes: blending the one or more thermoplastic polymers and the one or more bio-based flame retardant additives together at a temperature between 140&#xb0; C. and 230&#xb0; C. to form the polymer composite material; forming an article from the polymer composite material; and cooling the formed article.

Fiber-reinforced terephthalate-co-4,4'-bibenzoate copolyester behaves like a liquid crystalline polymer, providing fast crystallization, short cycling times, high Tand T, high strength and stiffness, while the viscosity is unexpectedly reduced at a low fiber loading ratio. In an injection molding process, the viscosity of the fiber reinforced copolyester at low fiber loading is reduced by increasing the fiber loading.

A method of forming an anisotropic porous material includes forming an aerogel precursor, the aerogel precursor including a matrix material and a liquid dispersion medium for dispersing the matrix material. The aerogel precursor is frozen so that the dispersion is solidified while controlling the direction of crystal growth within the aerogel precursor. The aerogel precursor is freeze dried to sublime the dispersion medium and form the porous material.

Low density, buoyant materials, in particular hydrophobic aerogels, may be used to absorb hydrophobic liquids. The materials are adapted to float on aqueous solutions and can absorb oils or other hydrophobic liquids from the surface of the solution without absorbing appreciable amounts of the aqueous solution. Methods for creating and using the materials are disclosed.

A method of forming a porous material having improved compressive strength, includes forming an aerogel precursor that includes a polymer having a functional group capable of undergoing a crosslinking reaction dispersed in a dispersion medium. The precursor also includes a crosslinking agent. The aerogel precursor is frozen so that the dispersion is solidified, and freeze dried to sublime the dispersion medium and form the porous material. The crosslinking agent is reacted with the functional group to effect crosslinking, thus improving the compressive strength of the porous material.

Diffusion barrier for electronic display devices

The present invention comprises a blend of polyester and a partially aromatic polyamide with an ionic compatibilizer and a cobalt salt. This blend can be processed into a container that has both active and passive oxygen barrier and carbon dioxide barrier properties at an improved color and clarity than containers known in the art. The partially aromatic polyamide is preferably meta-xylylene adipamide. The ionic compatibilizer is preferably 5-sodiumsulfoisophthalic acid or 5-zincsulfoisophthalic acid, or their dialkyl esters such as the dimethyl ester (SIM) and glycol ester (SIPEG). The cobalt salt is selected form the class of cobalt acetate, cobalt carbonate, cobalt chloride, cobalt hydroxide, cobalt naphthenate, cobalt oleate, cobalt linoleate, cobalt octoate, cobalt stearate, cobalt nitrate, cobalt phosphate, cobalt sulfate, cobalt (ethylene glycolate), or mixtures of two or more of these. The partially aromatic polyamide is present in a range from about 1 to about 10 wt. % of said composition. The ionic compatibilizer is present in a range from about 0.1 to about 2.0 mol-% of said composition. The cobalt salt is present in a range from about 20 to about 500 ppm of said composition.
