Abstract
Electrospinning technology was employed to fabricate a novel composite membrane integrating collagen from Peruvian squid skin with polystyrene (PS), polycaprolactone (PCL), and green-synthesized nickel oxide (NiO) nanoparticles (PS/PCL/CO/NiO). The addition of collagen (CO) and NiO nanoparticles significantly enhanced the membrane's hydrophobicity, as evidenced by an increase in the water contact angle from 124.8 ± 0.6° to 131.2 ± 1.2°. Mechanical properties showed substantial improvement, with tensile strength increasing by 86% (from 5.05 ± 1.6 MPa to 9.39 ± 1.4 MPa) and elongation at break improving by 48% compared to conventional NiO membranes. Thermal analysis indicated increased stability, with a higher endothermic peak and an enthalpy increase from 6.885 J/g to 8.584 J/g. Antibacterial assays revealed strong efficacy against Escherichia coli and Staphylococcus aureus, reducing bacterial growth by over 90%. The enhanced hydrophobicity, mechanical strength, thermal stability, and antibacterial activity of PS/PCL/CO/NiO membranes make them highly promising for applications in tissue engineering, wound dressings, and water treatment.
期刊介绍:
The word ‘particuology’ was coined to parallel the discipline for the science and technology of particles.
Particuology is an interdisciplinary journal that publishes frontier research articles and critical reviews on the discovery, formulation and engineering of particulate materials, processes and systems. It especially welcomes contributions utilising advanced theoretical, modelling and measurement methods to enable the discovery and creation of new particulate materials, and the manufacturing of functional particulate-based products, such as sensors.
Papers are handled by Thematic Editors who oversee contributions from specific subject fields. These fields are classified into: Particle Synthesis and Modification; Particle Characterization and Measurement; Granular Systems and Bulk Solids Technology; Fluidization and Particle-Fluid Systems; Aerosols; and Applications of Particle Technology.
Key topics concerning the creation and processing of particulates include:
-Modelling and simulation of particle formation, collective behaviour of particles and systems for particle production over a broad spectrum of length scales
-Mining of experimental data for particle synthesis and surface properties to facilitate the creation of new materials and processes
-Particle design and preparation including controlled response and sensing functionalities in formation, delivery systems and biological systems, etc.
-Experimental and computational methods for visualization and analysis of particulate system.
These topics are broadly relevant to the production of materials, pharmaceuticals and food, and to the conversion of energy resources to fuels and protection of the environment.
