Summary: In this study, a one-step scalable assembled PVA/TA complex coating was designed and fabricated to address the low oxygen barrier property of PLA film. By tailoring the mass ratio of PVA and TA, the oxygen barrier property of PLA film can be significantly improved. The research provides a convenient and efficient approach for the development of high oxygen barrier coatings.

Summary: Copolymers of N-isopropylacrylamide (NIPAM) and tetraphenylethene (TPE) acrylamide monomers with aggregation-induced emission (AIE) activity, namely P1, P2, and P3, were synthesized with relatively lower molecular weights (6000). These copolymers, similar to poly-N-isopropylacrylamide (p-NIPAM), showed fluorescence intensity change in response to temperature due to conformational transition (swelling/shrinking) below or above their lower critical solution temperature (LCST) in aqueous solution. The LCST of p-NIPAM (32 degrees C) decreased when TPE was incorporated into the copolymer chains, depending on the TPE concentration. The fluorescence response of P1 increased by five-fold with increasing tannic acid (TA) concentration, forming P1-TA complexes. Surprisingly, the fluorescence response of the P1-TA complex changed under the influence of temperature and pH value. Dynamic light scattering (DLS) measurements of P1-TA confirmed the fluorescence response based on particle size at different concentrations and pH values. These stimuli-responsive AIE-active copolymers show potential applications in monitoring drug loading and release processes in drug delivery systems using fluorescence.

Summary: Due to the biodegradable, biocompatible, sustainable, and renewable nature of biomaterials, there is a growing interest in developing biopolymer-based food packaging films using green ingredients and strategies. Green crosslinking technology, particularly using tannic acid as a natural crosslinker, has shown promising effects in improving the performance of biopolymer-based food packaging films. The crosslink of tannic acid not only enhances the properties of the films, but also contributes to food preservation.

Summary: The implementation of innovative packaging solutions in fresh food is becoming increasingly important in promoting sustainability. In this study, a novel GRAS preservative coating driven by intermolecular hydrogen bond self-assembly was demonstrated. The coating showed desirable antibacterial and antioxidant effects, good adhesion ability, and excellent performance in different packaging scenarios. It extended the shelf life of fresh-cut apples to 14 days and achieved high bactericidal rate and maintained sensory quality for fresh lettuce and beef. The proposed green and minimalist synthesis process also has the potential for scale-up production, making it a technological solution for future food development.
