Abstract
A chemical-resistant, user-wearable protective article. The article includes a first layer made of a polymeric material and a second layer made of a ceramic material. The second, ceramic material layer is coated onto the first layer. The first and second layers combined to form a flexible composite film that is shaped to be worn by a user as a barrier to chemicals. In one preferred embodiment, the second layer is aluminum oxide. Regardless, the film composite is preferably shaped as a glove, apron, etc., with the ceramic material coating providing a near perfect barrier to passage of most chemicals commonly employed in residential and industrial applications.
