A curable green epoxy resin composition is described. More particularly, the curable green epoxy resin composition includes a biobinder isolated from bio-oil produced from animal waste, such as from swine manure. The biobinder can act as a curing agent for an epoxy resin component in the resin composition. Cured green epoxy resins, prepregs containing the curable green epoxy resin, and related composite materials are described. In addition, methods of preparing the curable green epoxy resin composition and of curing the curable green epoxy resin.

Green epoxy resin with biobinder from manure

A method of synthesizing mechanically resilient titanium carbide (TiC) nanofibrous felts comprising continuous nanofibers or nano-ribbons with TiC crystallites embedded in carbon matrix, comprising: (a) electrospinning a spin dope for making precursor nanofibers with diameters less than 0.5 J.Lm; (b) overlaying the nanofibers to produce a nano-fibrous mat (felt); and then (c) heating the nano-felts first at a low temperature, and then at a high temperature for making electrospun continuous nanofibers or nano-ribbons with TiC crystallites embedded in carbon matrix; and (d) chlorinating the above electrospun nano-felts at an elevated temperature to remove titanium for producing carbide derived carbon (CDC) nano-fibrous felt with high specific surface areas.

The presently disclosed subject matter relates generally to antifungal nanofibrous materials and the use of such materials.

Antifungal compositions and methods of use thereof

The present application discloses carbonaceous nano-fibrous materials developed by electrospinning mixtures of alkali lignin with a polymer at varied mass ratios. The present application also discloses processing of the lignin/polymer fibers via progressive heat treatments for stabilization, pre-carbonization and carbonization. The resulting carbon nanofibers maintain a uniform shape and have high specific surface area.
