2025年2月1日 · The key to these pressure sensors is the preparation of mechanically-enhanced structures formed from a composite of surface patchy protrusions structures and porous structures using MXene 2D material as a layer conductive material with …

In this paper, low-density and flame-retardant (FR) porous fiber networks are prepared by assembling Layer-by-Layer (LbL)-functionalized cellulose fibers by means of freeze-drying.

2011年12月1日 · Brief overview to micro structural analysis of cellulose. SEM and TEM techniques to study various manifestations/morphologies of cellulose. Special sample preparation techniques and application of ESEM.

The processing of substrate and photothermal materials into porous materials is one of the popular methods. The porous structure can adsorb a large number of water molecules, resulting in formation of water clusters. ... SEM images of cellulose hydrogels (b) CNH1, (c) CNH2, (d) CNH3, (e) FT-IR spectrum of cellulose hydrogels, (f) XPS spectrum ...

The ion exchange membrane is essential for efficiently converting the salt differential gradient energy of the salinity gradient into electrical energy. Herein, we reported a sustainable, porous cellulose membrane (PCM) by a doping-removing strategy of polyvinyl pyrrolidone (PVP) during the fabricating process of the cellulose membrane.

2025年2月8日 · SEM showed that filters without additives had high porosity, but the porosity is non-uniform, in contrast, filters containing CST and PVA demonstrated high and more uniform porosity. ... S.H. Ji, J.S. Yun, Highly porous-cellulose-acetate-nanofiber filters fabricated by nonsolvent-induced phase separation during electrospinning for PM2.5 capture ...

2024年10月28日 · The protonated chitosan forms strong electrostatic attractions with negatively charged cellulose nanofibrils (CNF), achieving a robust interfacial interaction. Leveraging the hierarchically porous structure and varying hygroscopicity of microfibrillated cellulose (MFC) and CNF, the film establishes an effective wettability gradient, enabling a ...

2 天之前 · Figure 4 displays SEM images that compare common composite air filter paper (CAFP) with antibacterial composite air filter paper (CAFP DAC@Ag). The images illustrate a well-interlaced and stacked fiber structure in both types of composite air filter papers, which contributes to a highly porous network conducive to air filtration.

2021年6月4日 · Decellularization–recellularization approach was used to fabricate seaweed cellulose-based scaffolds for in-vitro mammalian cell growth. Both scaffolds were confirmed nontoxic to fibroblasts,...

2022年3月4日 · Generally, cellulose films obtained from solutions in NMMO have a higher permeability and a lower rejection (as measured using Orange II dye) as compared to cellophane films. It was also found that the cellulose films have a higher ultimate strength and modulus, whereas the cellophane films are characterized by higher elongation at break. 1.
