Abstract: This invention relates to a a one-step process for making a polymer composite suspension for coating plastic films characterized in that a first polymer is synthesized in-situ optionally in the presence of other polymers and in the presence of clay. Preferably the polymer composite suspension comprises a) 1.0 to 11.0 wt % of clay or silane modified clay, b) 0.1 to 10.0 wt % of poly (acrylic acid), which is a copolymer of acrylic acid (AA) with at least one other monomer selected from 2-ethylhexyl acrylate (EHA), β-carboxyethyl acrylate (β-CEA), methacrylamidoethyl ethylene urea (WAM II) and ethoxylated behenyl methacrylate (β-EM), c) 1.0 to 15.0 wt % of other polymers, preferably poly (vinyl alcohol) and d) 70 to 97 wt % of water or mixture of water with 2-propanol. The coating films made from the suspensions show good barrier capabilities against water vapor and oxygen can be used to make barrier layers on or within plastic films for packaging applications. The invention also relates to methods for making silane modified clay usable in the process for making the suspensions.

Abstract: A method of forming a titania-coated inorganic particle comprising the steps of (a) stirring a mixture of a titania precursor such as a titanium alkoxide and an inorganic particle such as a hollow glass particles in an organic solvent such as an alcohol for more than 1 h to cause adsorption of the titania precursor on the surface of the inorganic particle; and (b) adding water dropwise to the mixture under stirring to convert the titania precursor to titania which then forms a coating on the inorganic particle. A method for forming a paint formulation, a titania-coated inorganic particle, a paint formulation comprising a titania-coated inorganic particle and use of a titania-coated inorganic particle in a paint formulation is also described.

Abstract: A conductive carbonaceous fiber is provided, comprising a carbonaceous material obtained from carbonizing an electrospun fiber wherein said fiber comprises at least one conductive metal precursor. The electrospun fibers can be formed into fibrous mats during spinning, stabilization and carbonization that are conductive materials which can be used to make stretchable conductors for flexible electronic devices. The invention relates also to the process for making the fibers, corresponding elastomeric fibrous mesh/polymer composites as well as use of these composites for making stretchable electrical conductors. The obtainable elastomeric composite films (with a thickness in the range of 0.8 to 1.5 mm) exhibit good electrical conductivity and excellent electromechanical stability under mechanical deformations (e.g. elongating, twisting and bending). The scalable fabrication process and low-cost precursors make the elastic electrospun carbon fibers/polymer composite conductors promising materials for applications in flexible electronic devices, displays, sensors, wearable conducting clothes, implantable medical devices, etc.

Abstract: The invention is directed to a nanostructured composite material comprising a mixture of at least one metal particle such as iron and a carbon material from biomass such as D-glucose, D-glucosamine hydrochloride or a-cyclodextrin. The invention is also directed to a composition comprising the composite material comprising the composite material and an inorganic salt, and a method for synthesizing the composite material comprising immersing the carbon material into a solution of metal ions, drying the impregnated carbon particle and subjecting the impregnated carbon particle to a carbothermal reduction process. The nanostructured composite material is useful as an oxygen scavenging layer in a multi-layer film which comprises the oxygen scavenging layer and an oxygen barrier layer that retards the permeation of oxygen from an external environment.
