With a total of 3 patents, his work has had a considerable impact on various applications, including security control laminates.

Latest Patents

James D Smith's latest patents include innovative designs for tear-resistant multilayer films based on sebacic acid copolyesters. One of his patents describes a tear-resistant film that comprises at least three layers arranged in a parallel array. These layers are selected from a stiff polyester or copolyester, a ductile sebacic acid-based copolyester, and optionally, an intermediate material. The tear resistance of these films can be measured using a Graves area test, which reflects their ability to absorb energy. These films are particularly useful in security control laminates for glazing members. Another patent details a tear-resistant film that consists of more than five layers, also arranged in a parallel array. Similar to the previous patent, the layers are selected from a stiff polyester or copolyester and a ductile polymeric material, with the stiff polyester oriented in at least one direction. This innovation further enhances the tear resistance and energy absorption capabilities of the films.
