Abstract: (Co)polymer matrix composites including a porous (co)polymeric network; a multiplicity of thermally-conductive particles, and a multiplicity of endothermic particles distributed within the (co)polymeric network structure; wherein the thermally-conductive particles and endothermic particles are present in a range from 15 to 99 weight percent, based on the total weight of the particles and the (co)polymer (excluding the solvent). Optionally, the (co)polymer matrix composite volumetrically expands by at least 10% of its initial volume when exposed to a temperature of at least 135° C. Methods of making and using the (co)polymer matrix composites are also disclosed. The (co)polymer matrix composites are useful, for example, as heat dissipating or heat absorbing articles, as fillers, thermal interface materials, and thermal management materials, for example, in electronic devices, more particularly mobile handheld electronic devices, power supplies, and batteries.

Abstract: One or more embodiments of a respirator that includes a polymeric netting is disclosed. The respirator can include a mask body including a perimeter, a harness attached to the mask body, and a face seal disposed adjacent at least a portion of the perimeter of the mask body. In one or more embodiments, the face seal includes a polymeric netting including polymeric ribbons and polymeric strands, where each of the polymeric ribbons and strands having a length, width, and height, where the length is the longest dimension, the width is the shortest dimension, and the height is the dimension transverse to the length and the width. The polymeric ribbons have a height-to-width aspect ratio of at least 5 to 1, a major surface that is intermittently bonded to only one polymeric strand, and a height that is at least two times greater than a height of the one polymeric strand.

Abstract: Polymeric layers (50) comprising an array of blind openings (56) extending into the first major surface (52, 10111, 11211), but not through the second major surfaces (54, 10112, 11212). The blind openings each have a series of areas through the openings from the first major surface towards the second major surfaces ranging from minimum to maximum areas, where for at least a majority of the blind openings the minimum area is not at the first major surface. At least a portion of the first major surface comprises a first material and extends up to, but not into the second major surface. At least a portion of the second major surface comprises a second, different material. Methods for making the polymeric layers are also disclosed. Polymeric layers are useful, for example, as components in personal care garments such as diapers and feminine hygiene products. They can also be useful for filtering (including liquid filtering) and acoustic applications.

Abstract: A discontinuous silicone article is disclosed that includes a plurality of strands of radiation cured silicone gel arranged to form a net-like structure with openings between strands. The silicone gel provides adhesion to a surface, such as skin, and the openings provide for moisture transmission away from the surface. The discontinuous silicone article comprises at least one adhesive polymer strand and a plurality of joining strands. The adhesive polymer strands comprise a radiation cured silicone gel and each polymer strand repeatedly contacts an adjacent joining strand at bond regions.
