Bionic electronic skin, with its integrated biological functions, is capable of sensing and responding to external stimuli, potentially surpassing the ideal flexibility natural skin in certain aspects. Most current preparation strategies employ "bottom-up" approach, using various monomers or polymer materials construct artificial networks through physical chemical cross-linking, leading issues complexity limited performance. In this work, we adopted a "top-down" strategy, which collagen fiber network aluminum-tanned sheepskin was utilized as scaffold load itaconic acid (IA) hydroxyethyl acrylate (HEA). The subsequent situ polymerization IA HEA led formation poly(itaconic acid-co-hydroxyethyl acrylate) (P(IA-HEA)) filling among skeleton, results successful fabrication high-strength bionic based on (LIHEZ). advantage approach that it can retain structure properties give resulting LIHEZ multiple functions (e.g., electrical conductivity, adhesion, bacteriostasis, biocompatibility, environmental stability), thereby replicating even performance animal skin. demonstrated sensitive stimulus responsiveness durability could serve multimodal sensors (strain, temperature, humidity, bioelectricity) efficiently monitor human movements, physiological signals, changes temperature humidity. This diversified data collection provides reliable assurance for monitoring health. present construction method substrate not only breaks conventional single applications but also new insights selection flexible device substrates, promising be next-generation material constructing intelligent

This study aimed to pioneer the development of an innovative, eco-friendly, and chrome-free tanning agent, with a focus on promoting sustainable practices in ecological leather production. Two novel biomass-derived agents, namely, β-TCD β-GCD, were synthesized through one-pot grafting process involving environmentally friendly epoxy monomers: triglycidyl isocyanurate (TGIC) glycerol ether (GTE). Characterization various analytical methods, including FTIR, 1H NMR, XPS, GPC, SEM, TGA, confirmed successful TGIC GTE onto β-cyclodextrin (β-CD) backbones. The resulting β-GCD exhibited notable epoxide values 0.349 0.388 mol/100 g, respectively, along broader molecular weight distribution intermediates. These newly developed then applied depickling goatskin experiments. Results indicated that crust tanned displayed favorable thermal stability, shrinkage temperatures reaching 84 82 °C, respectively. Moreover, thickening rates exceeded 40%. leathers β-TCD, demonstrated excellent physical mechanical properties, as well resistance yellowing compared conventional commercial agents like TWS F-90.

Leather is produced by a multi-step process among which the tanning phase most relevant, transforming animal skin collagen into stable, non-putrescible material used to produce variety of different goods, for footwear, automotive, garments, and sports industry. Most leather today tanned with chromium (III) salts or alternatively aldehydes synthetic tannins, generating high environmental concern. Over years, exhaustion systems have been developed reduce impact salts, nevertheless do not avoid use metals. Chrome-free alternatives such as phenol based are suffering from Reach restrictions due their toxicity. Thus, need environmentally benign economically sustainable agents increasingly urgent. In this review, synthesis, mechanism new class agents, 1,3,5-triazines derivatives, reported together organoleptic, physical mechanical characteristics produced. Additionally performance economic data available compared those standard basic sulphate process, evidencing potentiality sustainable, metal, aldehyde, free manufacturing.

Abstract Biodegradability is a crucial indicator to evaluate the sustainability of leather. Herein, rapid method for biodegradation test in an aqueous medium by measuring biochemical oxygen demand was used determine biodegradability leather from different tanning methods, conditions and process stages. In addition, difference between leather-like synthetic materials were investigated. Chrome-free tanned showed higher degree faster rate than chrome Among them, leathers with biomass-based agents much easier biodegrade because crosslinking network constructed biomass more susceptible microbial attack. The enhancement effects through changing methods (such as agent dosage, pH temperature) resulted decline biodegradability. Future development novel chrome-free technologies should balance these two aspects. post-tanning finishing stepwise decrease various chemicals applied bound during processing. Even so, finished still possessed significantly compared PU microfiber materials, demonstrating superior environmental natural results are expected provide support evaluation ecological properties green upgrade industry.

Abstract The policy of sustainable development, the need to save natural environmental resources, and use waste as raw materials in new production processes allow enzymes many industries. Enzymatic tanning chrome are two different methods used leather industry transform hides into a durable usable material. uses that biodegradable environmentally friendly. Additionally, enzymatic requires less water generates than tanning. Moreover, can result softer more flexible with better uniformity. Enzymes selectively break down collagen fibers, resulting even consistent product. combined technologies non-obvious finishing methodologies is forced by European Union regulations limiting hazardous substances generating significant amounts corrosive wastewater for environment. However, not perfect process; therefore, this work presents advantages disadvantages describes technological trends industry.

In the present work, tannin-modified whey protein isolate (WPI/tannin) aerogels were synthesized, and their hydration properties evaluated. The materials prepared by introducing two different tannins (one hydrolyzable one condensed) in matrix via thermal-induced gelation of neutral or alkaline aqueous solutions (pH 7, 9, 11) at 80 °C. WPI WPI/tannin are nanostructured porous with high BET surface areas (216–353 m2 g–1). Subsequently, hydrophobized silanization (with bis(trimethylsilyl)amine) gas phase (HWPI HWPI/tannin aerogels). As a result silanization, reduced to 87–242 g–1. all studied measuring water uptake contact angles. Pristine absorbed amounts (up 4794% w/w 24 h), swelled, eventually disintegrated. condensed tannin more (219–559% w/w) than those (81–88% w/w). any case, was significantly lower compared that pristine aerogels.
