Methods for synthesis of high surface area porous silicon-based materials and structures that can be formed according to the methods are described. Methods are scalable and capable of producing large quantities of the high surface area materials with high efficiency. The high surface area products can be in the form of a 3D network of interconnected arms or quills with multimodal porosity including high level pores between and among arms, hollow cores of the arms of the network, and pores through the walls of the arms of the network.

Hollow porous silicon-containing structures and method of formation

This system and method provide for manufacturing a multi-material hybrid structure comprising a single- or multi-layer sheet or tube, which are made of metals, fabrics, polymer and their combinations, and at least one layer or body made of formed resin. The methods include a simultaneous forming-injection process that followed with an additional sequence to initiate the forming process along with curing and/or solidification and/or bonding processes. The additional sequence provides a pressure drop inside the cavity using tool movement and or additional deformation of one/or several layers of the sheet using any fluid pressure, suction and/or electromagnetic force. The injection process can be used for any kind of synthetic or bio-based resin with or without fiber reinforcement. It is also integrated with supercritical assisted technology.
