Abstract
A composite film adhereable to a surface of an object for changing its thermal and optical properties. According to one preferred embodiment the composite film includes a substrate, a non stoichiometric aluminum oxide layer deposited on one side of said substrate, and an adhesive layer for coating said non stoichiometric aluminum oxide layer, whereby said composite film is adhereable to a surface of said object. According to a second preferred embodiment the composite film includes a substrate, a first aluminum metal layer deposited on one side of said substrate, an aluminum oxide layer deposited on said first aluminum layer, a second aluminum layer deposited on said aluminum oxide layer, and an adhesive layer for coating said aluminum oxide layer, whereby said composite film is adhereable to a surface of said object. According to yet another preferred embodiment of the present invention the composite film includes a substrate, a first aluminum oxide layer deposited on one side of said substrate, an aluminum metal layer deposited on said first aluminum layer, a second aluminum oxide layer deposited on said aluminum oxide layer and an adhesive layer for coating said aluminum oxide layer, whereby said composite film is adhereable to a surface of said object.
