A method for preparing a conductive biomimetic skin scaffold material with self-repairing function includes the following steps: adding 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride to a homogeneous dispersion of acidified carbon nanotubes, poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), and gelatin to cross-link to obtain a conductive composite colloid; and injecting the conductive composite colloid into a mold, aging at &#x2212;4-4&#xb0; C. for 12-24 hours, and then soaking in a phosphate-buffered saline (PBS) solution with a pH of 7.0-7.4 for 12-24 hours to obtain the conductive biomimetic skin scaffold material.

A method for preparing a collagen from a chromium-containing tanned leather waste is disclosed. The method includes acid dechromation, obtaining a collagen aggregate, and converting the collagen aggregate to the collagen. The method also includes a reaction in a supercritical carbon dioxide reactor.
