Abstract:
The present invention relates to optical elements comprising fluorochemical surface treatments. The invention further relates to materials such as retroreflective sheetings, pavement markings and beaded projection screens comprising a binder and the surface treated optical elements. The fluorochemical surface treatment is substantially free of perfluoroalkyl groups having more than four carbon atoms. Preferably, the surface treatment is a polyfluropolyether-based compound comprising at least one polar group or polar group-containing organic radical.
Abstract:
This invention relates to foams made by polymerizing high internal phase emulsions (HIPE) containing polyelectrolytes. The emulsions comprise a continuous oil phase and a co- or discontinuous aqueous phase. The resulting foams are useful as a separations medium.
Abstract:
The present disclosure generally relates to durable solar mirror films, methods of making durable solar mirror films, and constructions including durable solar mirror films. The present disclosure generally relates to solar mirror films including a weatherable layer having a first major surface and a second major surface; and multiple discrete regions of reflective material adjacent to the first major surface of the weatherable layer. The present disclosure also generally relates to methods of making a solar mirror film involving providing a weatherable layer having a first major surface and a second major surface; and forming multiple discrete regions of reflective material adjacent to the first major surface of the weatherable layer.
Abstract:
A biological soil detector and a method for detecting bio soil are provided. The biological soil detector comprises: A solid support member; a specific indicator immobilized on the solid support member, the specific indicator comprising a material sensitive to the presence of blood; and the solid support and specific indicator positioned with respect to the detector to facilitate contact with a liquid that has been used to contact a surface. In the method for detecting bio soil, the method comprises: Contacting the surface with a liquid; after the liquid has contacted the surface, contacting the liquid with the solid support member and the specific indicator of the detector described herein; and inspecting the solid support member for a detectable response to determine whether the specific indicator has interacted with biological soil.
