Insights into functional polymer-based organic-inorganic nanocomposites as leather finishes

Abstract

Nowadays, the increasing demands from consumer challenges the traditional leather products. Traditional polymer leather finishes gradually lose their dominant position in the market. To address this issue, recent research effort has been devoted to developing polymer-based organic-inorganic nanocomposite leather finishes due to their various functional properties including antibacterial, self-cleaning and water-resistant property. In this review, we provide a comprehensive overview of synthesis of polymer-based organic-inorganic nanocomposites and their application as functional leather finishes. With the perspective of their properties and current challenges, an outlook in the future development about crafting functional and high-quality leather finishes are further proposed.

Experimental dehydration of wet fibrous materials

“…The study in [1] describes the current trend in applying vegetable tanning technology and wet processing methods based on new solvents, ionic and other liquids when solving the problem of using chromium in the leather industry. In [2][3][4][5][6][7][8][9][10][11], the influence of the technology of liquid, chemical, and mechanical treatment on the properties of leather collagens and its deformation and filtration parameters was studied. In [12], a review of 39 peer-reviewed articles in English devoted to the study of leather processing is given, of which 30 articles were published in the last 6 years.…”

Lightweight and Flexible Bi@Bi-La Natural Leather Composites with Superb X-ray Radiation Shielding Performance and Low Secondary Radiation

“…These structural advantages can promote stable integration and uniform dispersion of abundant high-Z elements in NL. NL features of remarkable mechanical property, tailorability, and durability demonstrate an ideal candidate matrix for X-ray shielding materials. , …”

“…NL features of remarkable mechanical property, tailorability, and durability demonstrate an ideal candidate matrix for X-ray shielding materials. 25,26 Some studies on natural leather-based X-ray shielding materials have realized satisfactory performance at 20−120 keV by impregnating bismuth as the functional element. 27,28 However, the shielding performance in 40−83 keV still needs improvement because of the weak absorption region of bismuth in this X-ray energy range.…”

Development and characterization of biodegradable compound based on EPDM and wood waste

“…Wood waste is classified by European standards as common waste, not hazardous or toxic to the environment. The transformation of waste (cryogenically ground and functionalized) into new valueadded products will lead to remarkable improvements in the life cycle of raw materials and sustainable use of this waste, contributing to increasing sustainability, improving eco-efficiency and economic efficiency and reducing the "pressure" of environmental waste (Alexandrescu et al, 2019;Zhu et al, 2017;Fan et al, 2019).…”
