Provided are a multilayered-coating system and a method of manufacturing the same. The multi-layered coating system includes: a layer 1 including a plurality of spherical voids with a radius a.sub.1 that are randomly distributed and separated from one another and a filler material with a refractive index n.sub.1 that is disposed in a space between the spherical voids; and subsequent layers expressed as the following word-equation, “a layer i located above a layer i−1 and including a plurality of spherical voids with a radius a.sub.i that are randomly distributed and separated from one another, and a filler material with a refractive index n.sub.i, the filler material disposed in a space between the spherical voids where i is an integer greater than 1”.

A stretched and foamed plastic formed body forming, in at least a portion thereof, a foamed region which incorporates foamed cells therein, wherein the foamed cells have a flat shape with a maximum thickness of not more than 30 μm and an average aspect ratio of not less than 4 as viewed in cross section of the formed body perpendicular to a direction in which the formed body is stretched to a maximum degree, and a non-foamed plastic skin layer having no foamed cell distributed therein is formed on the outer surface of the foamed region. The formed body is, further, blended with a non-lustrous pigment as the coloring agent, which is different from a lustrous pigment such as flaky pigment, and exhibits a metal color over the foamed region thereof. The foamed formed body exhibiting a metal color and, specifically, a gold color or a silver color is thus provided without using any expensive lustrous pigment such as metal powder pigment or flaky pigment.

A microporous membrane is made by a dry-stretch process and has substantially round shaped pores and a ratio of machine direction tensile strength to transverse direction tensile strength in the range of 0.5 to 5.0. The method of making the foregoing microporous membrane includes the steps of: extruding a polymer into a nonporous precursor, and biaxially stretching the nonporous precursor, the biaxial stretching including a machine direction stretching and a transverse direction stretching, the transverse direction stretching including a simultaneous controlled machine direction relax.

Porous hybrid inorganic/organic materials comprising ordered domains are disclosed. Methods of making the materials and use of the materials for chromatographic applications are also disclosed.

Composite materials having superior material properties useful as impact absorbing devices can be fabricated by embedding a lattice structure (e.g., polymer lattice structure) within a foam, so that the foam reinforces the lattice structure under impact. Materials and dimensions of the foam and the lattice structure may be selected to achieve composite materials having tailored impact absorbing elastic and/or viscoelastic responses over a wide range of temperatures.

The present invention relates to a double glazed window of a polycarbonate layer and, specifically, to a double glazed window of a polycarbonate layer, comprising an outer glass layer and an inner polycarbonate layer so as to have improved heat insulation and earthquake resistance. The double glazed window of a polycarbonate layer comprises: a glass layer forming an outer layer; a polycarbonate layer forming an inner layer; a vacuum layer (VL) formed between the glass layer and the polycarbonate layer; and sealing means for sealing the VL while coupling the glass layer and the polycarbonate layer.
