This paper presents a comprehensive review on the current state of digital simulation technology and its strategic application usages with a key focus on advanced compression garments. Although three-dimensional (3D) digital garment simulators have significantly impacted the apparel and textile industry, their use has been limited to visual prototyping, quality checking, or marketing. The physical properties of garment simulators have been overlooked in advanced functional manufacturing. This literature review investigates the possibility of strategically utilizing virtual physical properties to enhance garment functions, specifically in wearables and medical-grade compression fields. The first phase of this paper gives an overview of the current state of 3D garment simulation tools and their measurement features. This is followed by a gap analysis between simulated and physical property evaluations, focusing on minimizing the gaps. The literature is thoroughly examined to identify appropriate studies that uses digital tools for compressional garments and add value to wearables and healthcare applications. This paper provides valuable insights for apparel and textile engineers, enabling them to better understand the limitations and capabilities of garment simulators in improving advanced features for specific end users. © TBIS 2023.

Separators have an important influence on the safety and performance of lithium-ion batteries (LIBs). However, traditional polyolefin-based separators suffer from poor thermal stability and weak electrolyte wettability. Here, by using hydroxyapatite (HAP) and cellulose nanofibers (CNFs) as raw materials, we fabricated a unique HAP/CNF hybrid separator. The separators exhibit excellent thermal properties, with high thermal stability (up to 250 °C) and outstanding flame retardancy. The separators also demonstrate excellent electrolyte wettability. Compared to polypropylene (PP) separators, the HAP/CNF separators show a smaller contact angle with electrolytes, 17.2° for HAP/CNF and 45.5° for PP. Meanwhile, the HAP/CNF separators illustrate an excellent smoothness of 68.0 nm. In addition, the batteries assembled with the hybrid separators display a better performance compared with the batteries assembled with commercial PP separators. The raw materials are green, and the fabrication processes are free of organic solvents. We envision that the HAP/CNF hybrid separator could be a promising separator candidate for next-generation high-safety and high-performance LIBs. © 2023 American Chemical Society.

Silk fibroin membranes from solvent-crystallized silk fibroin/gelatin blends: Effects of blend and solvent composition

引用

Materials science and engineering C 2007年第3期27卷 426-431页

作者： Gil, Eun S. Frankowski, David J. Hudson, Samuel M. Spontak, Richard J.

Protein membranes have been prepared by mixing gelatin (G) with Bombyx mori silk fibroin (SF) and using aqueous methanol (MeOH) to induce SF crystallization. Amorphous blends of these polymers appear quasi-homogeneous, as discerned from visual observation, electron microscopy and Fourier-transform infrared (FTIR) spectroscopy. Upon subsequent exposure to aqueous MeOH, SF undergoes a conformational change from random-coil to β-sheet. This transformation occurs in pure SF, as well as in each of the G/SF blends, as discerned from FTIR spectroscopy and thermal calorimetry. The influence of MeOH-induced SF crystallization on structure and property development has been measured as functions of blend and solvent composition. By preserving a support scaffold above the G helix-to-coil transition temperature, the formation of crystalline SF networks in G/SF blends can be used to stabilize G-based hydrogels or generate SF membranes for biomaterial, pharmaceutical and gas-separation purposes. The present study not only examines the properties of G/SF blends before and after SF crystallization, but also establishes the foundation for future research into thermally-responsive G/SF bioconjugates. © 2006 Elsevier B.V.
