Abstract: Hybrid materials are formed having a homogeneous distribution of a conductive organic polymer or copolymer in an inorganic matrix. The conductive organic polymer may be electronically conductive, e.g., polyaniline, or may be ionically conductive, e.g., sulfonated polystyrene. The inorganic matrix is formed as a result of sol-gel chemistry, e.g., by the hydrolysis and condensation of tetraethyl orthosilicate and trialkoxysilyl groups in the organic polymers.

Abstract: A method for the prevention of blocking in Linear Low Density Polyethylene (LLDPE) films is provided, said method comprising the incorporation of at least a preselected High Density Polyethylene (HDPE) resin and a slip additive into the LLDPE film base resin at appropriate let-down ratios. The incorporation of the preselected HDPE resin and the slip additive into the film base resin can be accomplished in several ways. Regardless of the method of incorporation, after the extrusion and as the melt cools the preselected HDPE resin will give rise to the formation of larger crystals. Parts of these larger crystals will protrude from the film surfaces and trap the air, preventing it from being squeezed out from the gap in between two layers of film. Thus an antiblocking effect can be achieved without impairing the clarity, the gloss, the color, and the appearance of the film.
