Claim 22:
23. The multilayer microporous membrane or film of claim 22, wherein:
both outermost micro-layers or nano-layers of the outermost sub-membranes comprise polysiloxane or siloxane;
both outermost micro-layers or nano-layers of the outermost sub-membranes comprise polysiloxane or siloxane, wherein polysiloxane is present in an amount from 1 to 10 wt. % based on the total weight of the micro-layers or nano-layers;
both outermost micro-layers or nano-layers of the outermost sub-membranes comprise polysiloxane or siloxane, and the outermost micro-layers or nano-layers of the outermost sub-membranes also comprise, consist of, or consist essentially of polypropylene;
both outermost micro-layers or nano-layers of the outermost sub-membranes comprise polysiloxane or siloxane, wherein polysiloxane is present in an amount from 1 to 10 wt. % based on the total weight of the micro-layers or nano-layers, and the outermost micro-layers or nano-layers of the outermost sub-membranes also comprise, consist of, or consist essentially of polypropylene;
both outermost micro-layers or nano-layers of the outermost sub-membranes comprise polysiloxane or siloxane, and inner micro-layers or nano-layers of the inner sub-membrane comprise, consist of, or consist essentially of at least one of polypropylene, a polypropylene blend, polyethylene, or a polyethylene blend;
both outermost micro-layers or nano-layers of the outermost sub-membranes comprise polysiloxane or siloxane, wherein polysiloxane is present in an amount from 1 to 10 wt. % based on the total weight of the micro-layers or nano-layers, and wherein inner micro-layers or nano-layers of the inner sub-membrane comprise, consist of, or consist essentially of at least one of polypropylene, a polypropylene blend, polyethylene, or a polyethylene blend;
both outermost micro-layers or nano-layers of the outermost sub-membranes comprise polysiloxane or siloxane, and the outermost micro-layers or nano-layers of the outermost sub-membranes also comprise, consist of, or consist essentially of polypropylene, and wherein inner micro-layers or nano-layers of the inner sub-membrane comprise, consist of, or consist essentially of at least one of polypropylene, a polypropylene blend, polyethylene, or a polyethylene blend; or
both outermost micro-layers or nano-layers of the outermost sub-membranes comprise polysiloxane or siloxane, wherein polysiloxane is present in an amount from 1 to 10 wt. % based on the total weight of the micro-layers or nano-layers, and the outermost micro-layers or nano-layers of the outermost sub-membranes also comprise, consist of, or consist essentially of polypropylene, and wherein inner micro-layers or nano-layers of the inner sub-membrane comprise, consist of, or consist essentially of at least one of polypropylene, a polypropylene blend, polyethylene, or a polyethylene blend.
