Self-healing copolymeric materials comprising a plurality of intermediate strength crosslinks are provided. The copolymeric materials comprise a silicon component and a plurality of crosslinking components. The crosslinking components comprise a polymeric structure forming a structure held together by ionic and/or hydrogen bonding with a net intermediate strength. The plurality of intermediate strength crosslinks provide toughness to the material, and allow for rehealing by allowing reforming of the crosslinks after a disruptive stress incidence. The material is also suited for recasting, and can be used as an active matrix by incorporating additional substances. Articles of manufacture incorporating such materials, and methods of recasting such materials are also provided.

In some embodiments, the present invention provides novel methods of preparing porous silicon films and particles for lithium ion batteries. In some embodiments, such methods generally include: (1) etching a silicon material by exposure of the silicon material to a constant current density in a solution to produce a porous silicon film over a substrate; and (2) separating the porous silicon film from the substrate by gradually increasing the electric current density in sequential increments. In some embodiments, the methods of the present invention may also include a step of associating the porous silicon film with a binding material. In some embodiments, the methods of the present invention may also include a step of splitting the porous silicon film to form porous silicon particles. Additional embodiments of the present invention pertain to anode materials derived from the porous silicon films and porous silicon particles.In some embodiments, the present invention provides novel methods of preparing porous silicon films and particles for lithium ion batteries.

A design strategy for constructing hierarchically structured materials using nanoparticles and synthetic biopolymers has been developed. Block copolypeptides or homopolymer polyelectrolytes are used as structure-directing agents to arrange nanoparticles (composed of metals, metal non-oxides, metal oxides, or organics) into unusual microstructures, such as spheres, “apples” and “cups. ” Hollow spheres can be made wherein nanoparticles of one composition are spatially oriented completely interior or exterior to nanoparticles of a second composition. These aggregates contain nanoparticles only in the shell walls, and maintain their hollowness upon calcination. These shapes can also be fabricated into films. These robust materials are anticipated to have great promise in applications that require surface catalysis, magnetic/electronic/optic properties, transport capabilities, and combinations thereof, such as drug delivery, packaging, catalysis, and sensors.
