Abstract: A liquid infused membrane includes a porous fluorine-containing polymer membrane and a perfluoropolyether oil coating on at least a portion of the first surface and at least a portion of the pore wall. Advantageously, the liquid infused membrane does not exhibit gating. Methods for the manufacture thereof and uses of the liquid infused membrane are also disclosed.

Abstract: In an embodiment, a composition comprises a plurality of reactive particles; wherein at least a first portion of the reactive particles comprises a first reactive monomer located in a first matrix polymer; wherein the first reactive monomer comprises a self-reactive monomer or wherein the first reactive monomer can polymerize with a second reactive monomer located in a second matrix polymer of a second portion of the reactive particles to form a coating polymer. In another embodiment, a method of making the plurality of reactive particles, comprises polymerizing a first matrix monomer in the presence of the first reactive monomer; or polymerizing the first matrix monomer to form a plurality of particles and swelling the plurality of particles with the first reactive monomer. In another embodiment, a method comprises cold spraying the plurality of reactive particles.
