Vinyl acetate is an organic compound with the formula CH₃CO₂CH=CH₂. This colorless liquid is the precursor to polyvinyl acetate, an important industrial polymer.

Composite materials comprising polar polymers and single-wall carbon nanotubes

The invention relates to a composite comprising a weight fraction of single-wall carbon nanotubes and at least one polar polymer wherein the composite has an electrical and/or thermal conductivity enhanced over that of the polymer alone. The invention also comprises a method for making this polymer composition. The present application provides composite compositions that, over a wide range of single-wall carbon nanotube loading, have electrical conductivities exceeding those known in the art by more than one order of magnitude. The electrical conductivity enhancement depends on the weight fraction (F) of the single-wall carbon nanotubes in the composite. The electrical conductivity of the composite of this invention is at least 5 Siemens per centimeter (S/cm) at (F) of 0.5 (i.e. where single-wall carbon nanotube loading weight represents half of the total composite weight), at least 1 S/cm at a F of 0.1, at least 1×10−4 S/cm at (F) of 0.004, at least 6×10−9 S/cm at (F) of 0.001 and at least 3×10−16 S/cm (F) plus the intrinsic conductivity of the polymer matrix material at of 0.0001. The thermal conductivity enhancement is in excess of 1 Watt/m-° K. The polar polymer can be polycarbonate, poly(acrylic acid), poly(acrylic acid), poly(methacrylic acid), polyoxide, polysulfide, polysulfone, polyamides, polyester, polyurethane, polyimide, poly(vinyl acetate), poly(vinyl alcohol), poly(vinyl chloride), poly(vinyl pyridine), poly(vinyl pyrrolidone), copolymers thereof and combinations thereof. The composite can further comprise a nonpolar polymer, such as, a polyolefin polymer, polyethylene, polypropylene, polybutene, polyisobutene, polyisoprene, polystyrene, copolymers thereof and combinations thereof.

Mildewproof preservative film and preparation method thereof

The invention discloses a mildewproof preservative film and a preparation method thereof. The mildewproof preservative film comprises a base layer and a mildewproof preservative coating arranged on the base layer, wherein the mildewproof preservative coating is prepared from a mildewproof preservative paint. The mildewproof preservative paint comprises the following components in percentage by weight: 20-60% of resin, 30-70% of solvent, 0.5-10% of mildew preventive and 0.3-5% of aid. The resin is composed of at least one of polyurethane, an acrylate copolymer, polyvinyl alcohol, polyvinylidene chloride, modified polyvinylidene chloride, an ethylene-vinyl acetate copolymer, a polyvinyl acetate copolymer and a vinyl acetate-butyl ester copolymer; and the solvent is composed of at least one of water and ethanol. The mildewproof preservative coating of the mildewproof preservative film has the advantages of compact surface and no void; and by adding the mildew preventive, the mildewproof preservative coating has the favorable effects of keeping the moisture constant and preventing mildewing. The mildewproof preservative film is especially suitable for preserving fruits, bread, tobacco and other foods which have shorter storage period, can easily mildew in a short time and need to be eaten in time.
