Small, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 16, 2024

Developing antibacterial and biodegradable cellulose acetate (CA) membrane materials is one of the main challenges in multiple application fields. CA are widely used gas purification, water biomedical fields due to their environmental friendliness, high chemical mechanical stability, excellent processability, low cost. However, modification enhance utilization value process has always been direction researchers' efforts. This review focuses on preparation its derivatives membranes, especially types introduction methods agents. First, a brief CA-based polymer membranes presented, followed by an overview agent methods, mechanisms. After that, various prepared using polymers as matrix or additives discussed. Then, specific applications biomedical, food packaging, other outlined.

Rapid urbanisation and industrialisation have intensified the Urban Heat Island (UHI) effect, significantly increasing energy demand for thermal comfort. buildings consume considerable throughout year, which can be reduced by incorporating Phase Change Materials (PCMs) into building materials. PCMs effectively regulate temperature storing releasing heat as latent during phase transitions. However, to prevent leakage, encapsulated in co-axial polymeric Fibres (PCFs), representing an innovative approach scientific research. This study optimised coagulation bath produced PCFs using commercial cellulose acetate sheath polyethylene glycol (PEG 600 1000) core via wet-spinning method. The first part of this work investigated Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR) analyses characteristic peak areas. In contrast, second examined PCFs’ morphological, chemical properties Bright-field microscopy, ATR-FTIR, Differential Scanning Calorimetry (DSC) Thermogravimetric Analysis (TGA) techniques. results demonstrated successful production with bath. microscopy ATR-FTIR confirmed well-defined morphology presence PEG fibre core. TGA analysis showed high stability PCFs, mass loss observed at degradation temperatures, ranging from ~264 °C 397 ~273 413 1000. Meanwhile, DSC revealed melting points ~12.64 11.04 °C, endothermic enthalpy ~39.24 30.59 exothermic ~50.17 40.93 respectively, 600, ~40.32 41.13 ~83.47 98.88 ~84.66 88.79 These validate potential applications materials civil engineering, promoting efficiency structural stability.
