With more challenges facing traditional chemicals used for leather making, along with the development of higher living standards, great demand is imposed on the leather industry. Therefore, more researchers are paying attention to collagen modification using nanotechnologies for the leather industry. In this review, we present a critical discussion of collagen modified by nano-size emulsion, clay minerals, nano silicon dioxide, or nanosilver. In the end, we conclude this review with some perspectives on the future research and development of collagen modified by nanotechnology.

Preparation of acrylic resin/montmorillonite nanocomposite for leather tanning agent / Yan Bao in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. CIV, N° 10 (10/2009)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. CIV, N° 10 (10/2009) . - p. 352-358 Titre : Preparation of acrylic resin/montmorillonite nanocomposite for leather tanning agent Type de document : texte imprimé Auteurs : Yan Bao, Auteur ; Jian-Zhong Ma, Auteur ; Yan-Li Wang, Auteur Année de publication : 2009 Article en page(s) : p. 352-358 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Acrylic resin/montmorillonite (AR/MMT) nanocomposite was prepared using Na+-montmorillonite (Na+-MMT) via in-situ polymerization of hydrophilic monomer in aqueous medium. The synthetic conditions, such as the contents of MMT and ammonium persulfate (APS), the molar ratio of different monomers, and the dosage of sodium bisulfate on the application properties of nanocomposite were investigated in detail. The thickness increment ratio, the wet-heat resistance and the tensile, slit and burst strengths of leather tanned by AR/MMT were improved and elongations at break and given load were slightly reduced, in contrast to AR treatment; the wet-heat resistance and the physical / mechanical properties of leather tanned by 6% AR/MMT associated with 2% chromate were lower than 8% chromate tanned. As well, AR/MMT facilitates the absorption of chromate. Compared with conventional chrome tanning, the dosage of chromate is reduced 75%. Scanning Electron Microscope (SEM) pictures of leather samples indicated that the collagen fiber of leather samples tanned by AR/MMT was well dispersed when compared to AR and pure chromate treatment. X-ray Diffraction (XRD) and Transmission Electron Microscope (TEM) confirmed AR/MMT is an exfoliated nanocomposite.
