Abstract
Method for preparing porous polyurethane materials with controlled pore size and shape using isocyanates, polyols, and additives, and the porous polyurethane materials prepared therefrom. Method for preparing porous polyimides using at least one polyamine and a dianhydride and the porous polyimides materials prepared therefrom. The porous materials are useful for energy management, such as thermal, impact and vibration energy, and can exhibit improved fire-resistant performance.
Claims12
A method for preparing a porous polyurethane material, the method comprising:
- providing a first composition comprising an isocyanate and a polyol mixture, wherein the isocyanate comprises an aryl isocyanate and the polyol mixture is at least one hydroxyl terminated polyether polyol, ethylene glycol and hydroxyl terminated silicone oil;
- providing a second composition comprising at least one polyol, a blowing agent, optionally a pore forming agent, optionally a surfactant, a catalyst, and at least two solvents;
- and
- combining the first composition and the second composition thereby forming the porous polyurethane material.
