POROUS MATERIALS AND METHOD OF MAKING POROUS MATERIALS

Номер: US20180079883A1
Принадлежит:

A porous material includes a resin material based on a trifunctional ethynyl monomer. Pores in the porous material can be of various sizes including nanoscale sizes. The porous material may be used in a variety of applications, such as those requiring materials with a high strength-to-weight ratio. The porous material can include a filler material dispersed therein. The filler material can be, for example, a particle, a fiber, a fabric, or the like. In some examples, the filler material can be a carbon fiber or a carbon nanotube. A method of making a porous material includes forming a resin including a trifunctional ethynyl monomer component and a polythioaminal component. The resin can be heated to promote segregation of the components into different phases with predominately one or the other component in each phase. Processing of the resin after phase segregation to decompose the polythioaminal component can form pores in the resin. 1. A method , comprising:forming a mixture comprising: i) trifunctional ethynyl monomer, ii) a polythioaminal, and iii) a solvent;heating the mixture to a first temperature at which the trifunctional ethynyl monomer polymerizes to a first resin and the polythioaminal is substantially stable; andheating the mixture to a second temperature at which the first resin further polymerizes to a second resin that is a crosslinked resin and the polythioaminal decomposes, the second temperature being higher than the first temperature.2.
