Characteristics of laser printed waste paper fibers filled polybutylene adipate terephthalate (PBAT) based composite films

Polymer Composites, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 11, 2025

Abstract With the advancement of office automation, production and consumption laser‐printed waste paper have been increasing steadily, drawing considerable attention in industry for high‐value utilization this novel, high‐quality paper. PBAT (polybutylene adipate terephthalate) belongs to thermoplastic biodegradable polymers, offering a potential alternative conventional plastics addressing issues like microplastic pollution. However, high cost limits its widespread application. This study focuses on utilizing reinforcing PBAT‐based plastics, thereby developing novel film material conducting an in‐depth investigation properties. Results indicate that mechanical properties LPWF/PBAT composite are optimized when fiber (LPWF) content is at 20%. Furthermore, address poor compatibility between fibers resin interfaces, modifications were carried out using γ‐glycidoxypropyltrimethoxysilane(KH560), vinyltriethoxysilane(A151), maleic anhydride grafted PBAT(PBAT‐ g ‐MAH), cationic polyacrylamide(CPAM). The modified exhibited improved properties, water absorption, thermal stability. research provides insights design development low‐cost, high‐performance materials. Highlights Laser printed serve films. At 20 wt% LPWF, film's elastic modulus reaches 369 MPa. Adding 3 PBAT‐g‐MAH increases tensile strength by 33.6%. Four modification methods significantly enhance resistance A151 enhances stability

Enhanced Antioxidant and Antibacterial Properties of Polybutylene Adipate-Terephthalate/Curcumin Composite Films Using Surface-Modified Cellulose Nanocrystals

Polymers, Journal Year: 2025, Volume and Issue: 17(7), P. 830 - 830

Published: March 21, 2025

Polybutylene adipate-terephthalate (PBAT) offers a convincing ecological alternative to the traditional fossil-based plastics due its biodegradability and robust mechanical properties. The objective of this study is develop PBAT-based bio-composite films through incorporating functionalized cellulose nanocrystals (CNC) curcumin (CUR). In order improve interfacial compatibility with PBAT matrix co-doping CUR, CNC was modified using dodecyl succinic anhydride (DxCNC). ternary system, CUR functioned as bio-based antioxidant antimicrobial agent. presence also provides excellent UV-shielding properties, whereas DxCNC effectively enhances controlled release CUR. synergistic effect between in boosting inhibition values for E. coli S. aureus reached 1.82 log CFU/cm2 2.12 CFU/cm2, respectively. These findings indicate DxCNC/CUR/PBAT composite promising material eco-friendly packaging products.

Development of poly(butylene adipate‐co‐terephthalate) composites with high thermal oxidation stability using Chrysanthemum morifolium extract as a natural additive

Polymer Engineering and Science, Journal Year: 2024, Volume and Issue: 64(5), P. 2289 - 2300

Published: Feb. 24, 2024

Abstract Poly(butylene adipate‐co‐terephthalate) (PBAT) is one of the solutions to energy crisis and white pollution. However, poor thermo‐oxidative stability limits its wide applications. In this work, Chrysanthemum morifolium extract (CME) as a natural additive was used modify PBAT. The oxidation onset temperature (OOT) results showed that CME could provide PBAT with high thermal stability. By presence 2.5 wt% CME, OOT value PBAT‐CME increased by 52°C compared neat outstanding antioxidant capacity attributed excellent free radical quenching whose main components consist six kinds phenolic compounds. Moreover, 1.5 composite achieve balance between mechanical property stability, result 42°C, tensile strength reached 103.1%, elongation at break retain 91.4% Besides, processing property, degradation performance, surface hydrophobic nature modified samples were all improved. This work proposes facile method obtain completely biodegradable composites expand practical applications Highlights in are scavenging efficiency. improved matrix. addition still maintain good properties introduction promoted films.
