Abstract:
The present invention relates to a polymer composition having improved scratch resistance properties, the composition comprising (i) one or more polymers with a glass transition temperature (Tg) of at least 25° C., and (ii) solid particulate material having a surface modified with an organic modifier of formula (I), an organic modifier of formula (I) being the only organic modifier used to modify a surface of the solid particulate material, wherein the solid particulate material is distributed at least throughout a surface layer of the one or more polymers, and wherein the improved scratch resistance is relative to that of the one or more polymers absent the distributed particulate material, (I) where R is selected from a quaternary ammonium cation, a quaternary phosphonium cation, and imidazolium cation and a pyridinium cation; x is an integer ranging from 1-5; Ry is selected from OH, C(O)OH, NH2, SH and CH3; and Z is a counter anion.
Abstract:
A method includes contact printing an active composition onto a surface of a release substrate to form a printed surface. The active composition spontaneously dewets the surface of the release substrate to form active deposits on the surface of the release substrate. The active composition comprises an active agent dissolved or dispersed in an aqueous liquid vehicle. A pressure-sensitive adhesive layer is disposed on the printed surface.
Abstract:
The present invention is directed to a fluoropolymer tape having an electrically conductive surface. More specifically, the present invention is directed to a polytetrafLuoroethylene (PTFE) tape and method for producing an electrically conductive tape by blending vapor-grown carbon fiber or carbon nanotubes or combinations of both with PTFE.
Abstract:
The invention relates to the use of microparticles hydrophobized by fluorosilanes or fluorosiloxanes for the production of surfaces having self-cleaning properties and lactophobic, oleophobic and lipophobic properties. The use of microparticles hydrophobizated by fluorosilanes in known methods for the production of self-cleaning surfaces enable surfaces to be produced which have self-cleaning properties as well as lipophobic, oleophobic and lactophobic properties. Objects having said type of surface are particularly easy to clean, especially in cleaning impurities containing oil, fat or milk. The use of said invention is particularly suitable in the production of technical textiles, work clothes and children's clothing.
Abstract:
It is intended to provide a metal can from which the contents packed therein are easy to take out and which has been coated with a polyester resin film for food or with a film for food which is made of a resin consisting mainly of a polyester resin; a metal sheet which has been coated with a surface-roughened resin film and is for use in the metal can; a surface-roughened resin film for use in the metal sheet; and processes for producing these. The surface-roughened resin film is one which comprises a polyester resin and, incorporated therein, either inorganic particles or a resin incompatible with the polyester resin, e.g., a polyolefin resin, to thereby have a roughened surface. Alternatively, the surface-roughened resin film is one obtained by embossing a surface of a resin film. The surface-roughened resin film is laminated to a metal sheet. Alternatively, a resin film which has not undergone surface roughening is laminated to a metal sheet and this resin film-coated metal sheet is embossed. The resultant resin film-coated metal sheet is formed into a can by drawing or by drawing with ironing. The surface roughness is thus enhanced.
Abstract:
A conducting polymer-inorganic nanoparticle nanoarray is provided. Nanoparticles are formed and capped which provide enhanced properties to the nanoparticles and allow easier handling of them. The capping may be done when the nanoparticles are formed and may functionalize the nanoparticles. The nanoparticles are then bound to conducting polymers in order to produce an electrically conducting matrix which may in turn be electrically bound to a substrate to form an anode or cathode for a Lithium battery. In the matrix the nanoparticles are wired to each other electrically via the capping agent and/or the conducting polymer. The conducting polymer allows for repeated Li+ insertion in use as a battery anode or cathode.
Abstract:
In a silicone rubber composition comprising an organopolysiloxane having at least two aliphatic unsaturated groups and a curing agent, metallized particles of inorganic material or organic resin are effectively dispersed to give a conductive composition which cures into a conductive silicone rubber part having a low and stable volume resistivity.
Abstract:
A composite material having a structure in which negatively charged colloidal silica having an average particle diameter of not greater than 50 nm and remaining substantially in the form of primary particles is attached to the outer surfaces of negatively charged polymer particles. By using this composite material, there can be obtained molded articles wherein colloidal silica is dispersed in a resin while remaining substantially in the form of primary particles.
