Abstract
Methods of forming a composite material film can include providing a mixture comprising a precursor and silane-treated silicon particles. The methods can also include pyrolysing the mixture to convert the precursor into one or more carbon phases to form the composite material film with the silicon particles distributed throughout the composite material film.
Claims58
A method of forming a composite material film, the method comprising:
- providing a mixture comprising a precursor and silane-treated silicon particles;
- and
- pyrolysing the mixture to convert the precursor into one or more carbon phases to form the composite material film with the silicon particles distributed throughout the composite material film, wherein:
- silane-treated silicon particles comprise silicon particles treated with one or more organosilanes;
- the one or more organosilanes comprise one or more silanols, silyl ethers, silyl chlorides, dialkylaminosilanes, silyl hydrides, or cyclic azasilanes;
- and
- the one or more organosilanes comprise dodecylsilane.
