  • Publication number: 20220410075
    Abstract: A method for manufacturing of porous polymer structures, in particular membranes, the method comprising the steps of providing a mixture of one or more polymers and one or more salt nano- and/or microparticles, primary shaping said blend, and removing said one or more salt particles, wherein at least part of the one or more salt nano- and/or microparticles is one or more solid acids, and whereby the ratio of polymer-to-particle is in the range of 3:1 to 1:10 by weight. Also provided are mixtures suitable to obtain such porous polymer structures, porous polymer structures as described herein, shaped articles containing such structures, and the use of such porous polymer structures, shaped articles and mixtures.

  • Publication number: 20160250401
    Abstract: A pump having at least a fluid pump chamber (11) and a first driver chamber (12) separated from the fluid pump chamber (11) by an elastic wall (13, 13-1, 13-2) is described with the first driver chamber (12) expanding after a chemical reaction between fuel and oxidant and driving through deformation of the elastic wall fluid out of the fluid pump chamber (11), with the main parts of the pump being made of an elastic material to be used for example as a body implant.
