摘要： The present disclosure provides methods for forming asymmetric membranes. More specifically, methods are provided for applying a polymerizable species to a porous substrate for forming a coated porous substrate. The coated porous substrate is exposed to an ultraviolet radiation source having a peak emission wavelength less than 340 nm to polymerize the polymerizable species forming a polymerized material retained within the porous substrate so that the concentration of polymerized material is greater at the first major surface than at the second major surface.

摘要： Polymer matrix composite comprising a porous polymeric network; and a plurality of intumescent particles distributed within the polymeric network structure; wherein the intumescent particles are present in a range from 15 to 99 weight percent, based on the total weight of the intumescent particles and the polymer (excluding the solvent); and wherein the polymer matrix composite volumetrically expands at least 2 times its initial volume when exposed to at least one temperature greater than 135° C.; and methods for making the same. The polymer matrix composites are useful, for example, as fillers, thermally initiated fuses, and fire stop devices.
