Article Abstract
Our goal was to develop film-forming polymers to extend the antimicrobial lifetimes of cleaned and disinfected surfaces. Antimicrobial polymers were prepared by first reacting poly(ethylene-alt-maleic anhydride) with isopropylamine, partially consuming the anhydride groups, followed by hydrolysis to give water-soluble, highly anionic polyamide PC3. Chlorination with NaOCl gave PC3Cl with oxidative chlorine contents up to 9 wt%. Dried, 5 µm thick, PC3Cl films, gave log 4 reductions in the concentration of Escherichia coli or Staphylococcus aureus exposed to films. A unique feature of the maleic anhydride copolymer platform was the ability to form covalent grafts to surfaces via anhydride reactions. PC3 solution was impregnated into cellulosic filter paper, heated to form ester linkages with cellulose, followed by chlorination with sodium dichloroisocyanurate dihydrate giving grafted PC3Cl. The treated paper (0.3 wt% PC3Cl) gave a log 4 reduction of E. coli concentration in 30 min.

Developing MXene-based electromagnetic interference (EMI) shielding composite films with exceptional wet mechanical properties is crucial to address the limitation of conventional MXene-based EMI shielding composite films in humid environments. Herein, we present a fabrication strategy for Janus-structured MXene-based EMI shielding composite films with exceptional wet mechanical and Joule heating performances. Through depositing tannic acid-modified MXene (TM) on maleic anhydride-modified lignin-containing cellulose nanofibril (MLCNF) film using a scalable vacuum filtration and hot-pressing strategy.

Lignocellulosic materials derived from by-products such as cellulose typically provide enhanced interfacial properties when functionalized with coupling agents, such as maleic anhydride (MA), and incorporated into polylactic acid (PLA) polymers. This research aims to identify the optimal conditions for either improving or maintaining PLA properties evaluating interactions by incorporating varying amounts of cellulose (5-28 wt%) extracted from sawdust biomass and PLA-g-MA (3-20 wt%) composites into pure PLA. This is accomplished through an extreme vertices mixture design (EVMD).

Polylactic acid (PLA) materials face inherent limitations in many applications due to their low toughness. To address this challenge, this study employed a reactive melt-grafting method to prepare maleic anhydride (MA)-grafted poly(butylene adipate-co-terephthalate) (PBAT-MA), providing an effective approach to improve the interfacial compatibility between PLA and PBAT, thereby significantly enhancing the toughness and impact resistance of PLA and expanding its application scope. The grafting reaction process of PBAT-MA was investigated, as well as its toughening mechanism and effect on PLA.

Developing a drug delivery strategy that can cross the blood-brain barrier is crucial to effective neurological treatment. In this work, a new strategy was introduced for efficient drug delivery of Donepezil based on the preparation of polyelectrolyte complexes (PEC) nanogel from β-chitosan (CS) and the prepared sulfonated styrene-maleic anhydride (S-SMA). First, low-molecular-weight SMA was prepared.
