Chitinous Bioplastic Enabled by Noncovalent Assembly

ACS Nano, Journal Year: 2024, Volume and Issue: 18(12), P. 8906 - 8918

Published: March 14, 2024

Natural polymeric-based bioplastics usually lack good mechanical or processing performance. It is still challenging to achieve simultaneous improvement for these two usual trade-off features. Here, we demonstrate a full noncovalent mediated self-assembly design simultaneously improving the chitinous bioplastic and properties via plane hot-pressing. Tannic acid (TA) chosen as mediator (i) increase cross-link intensity obtaining tough network (ii) afford dynamic cross-links enable mobility of chitin molecular chains benefiting nanostructure rearrangement during shaping procedure. The multiple (chitin–TA chitin–chitin cross-links) pressure-induced orientation nanofibers structure endow with robust properties. relatively weak chitin–TA interactions serve water mediation switches enhance endowing chitin/TA hydroplastic properties, rendering them readily programmable into versatile 2D/3D shapes. Moreover, fully natural resourced exhibits superior weld, solvent resistance, biodegradability, enabling potential diverse applications. physical cross-linking mechanism highlights an effective concept balancing processability polymeric materials.

In Situ Fermentation of an Ultra-Strong, Microplastic-Free, and Biodegradable Multilayer Bacterial Cellulose Film for Food Packaging

ACS Applied Materials & Interfaces, Journal Year: 2023, Volume and Issue: 15(37), P. 44354 - 44363

Published: Sept. 12, 2023

Cellulose-based food packaging has a significant importance in reducing plastic pollution and also ensuring our safety from microplastics. Nonetheless, lignocellulose necessitates sophisticated physical chemical treatments to be fashioned into satisfactory packaging, thus leading extra consumption operations. Here, we present gel-assisted biosynthesis approach for the situ production of bacterial cellulose (BC) that can directly applied packaging. Komagataeibacter sucrofermentans is homogeneously distributed gellan gum (GG)-assisted culture system, BC/GG film with an even surface attained. Then, integrated antibacterial layer containing quaternary ammonium chitosan microsphere (QM) through spray method. The resulting BC/GG/QM multilayer combines barrier properties activity. method green, efficient, convenient endow excellent capacity (1.76 g·mm·m-2·d-1·KPa-1 at RH 75%), high mechanical (strength 462 MPa), activity (>90% against Escherichia coli O157:H7 Staphylococcus aureus). In terms preservation, overall performance better than commercial petroleum-based lignocellulose-derived film. This work proffers novel strategy produce more beneficial eco-friendly via biosynthesis, which manifests great utility field

Spontaneously formed cellulose-based random micro-textured film for light extraction in organic light-emitting diodes

Journal of Information Display, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 8

Published: March 5, 2024

This study utilized cellulose-based external light extraction films to enhance the outcoupling efficiency of organic light-emitting diodes (OLEDs). These were created through a straightforward fabrication employing biopolymers hydroxyethyl cellulose (HEC) and tannic acid (TA). We observed that hydrogen bonding between HEC TA could spontaneously generate random microtextured surface on HEC: films. Furthermore, morphology HECTA film can be adjusted by varying content. When applying as an light-extraction layer for OLEDs, we noticed remarkable improvement in quantum current OLEDs up 54% compared those without film. Additionally, displayed outstanding ability absorb ultraviolet light. Therefore, it is anticipated significantly contribute prolonging stability OLEDs.
