The coated carbon nanotubes may be used to stitch in a Z-direction into a composite such as a polymer prepreg to strengthen the composite. The stitching may occur using a sewing machine.

A one-step formed gel fiber composite scaffold material can be prepared by preparing an electrospun film through a high-voltage electrostatic method and soaking the electrospun film into a phase separation solution to obtain the gel fiber composite scaffold material. The obtained composite scaffold material is an extracellular matrix simulated composite material and can be modified by adding multiple natural biomaterials, so that the composite material is closer to an extracellular matrix in terms of components

A method of treating a material, the method comprising the steps of: (1) contacting the material with a composition comprising an electrophilic species selected from aldehydes, succinimidyl esters, and mixtures thereof; (2) contacting the material with a composition comprising a chelating agent and/or a salt of an amine and/or a carboxylic acid.
