Properties of a Solid–Solid Phase Change Material PAN/SA-LA/ZMS

Applied Mechanics and Materials (2014)

Jing Guo Xiang Kang You Li Zhang Hengxue Xiang Sen Zhang

In this study, novel solid–solid phase change materials (PCM) composed of polyacrylonitrile, binary of fatty acids ((blending of stearic acid (SA) and lauric acid (LA)) and zeolite molecular sieve (ZMS) were prepared by solution blending process. The structure and properties of the PCM were characterized using flourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), polarized optical microscopy (POM), differential scanning calorimetry (DSC) and thermogravimetric analysis (TG), respectively. DSC analysis indicated that the crystallization latent heat of the PCM was 125.22 J/g and its phase transition temperature was about 17 °C. The temperature curve for step cooling of the PCM showed that it’s holding time achieved 1 480 s, which explains that the PCM had excellent heat-insulating properties. Based on all results it can be concluded that the novel PCM can be considered as potential PCM for thermal energy storage.

MD Simulations of Nanoparticle Thermal Conductivity and Nanoscale Thermal Contact Resistance

First International Conference on Integration and Commercialization of Micro and Nanosystems, Parts A and B (2007)

Hengxue Xiang Peixue Jiang Qixin Liu

The rapid progress and development of the synthesis and processing of materials with structures having nanometer length scales has created a demand for greater scientific understanding of thermal transport in nanoscale devices. Molecular dynamics (MD) simulations are emerging as a powerful tool for studying thermal conductance and phonon scattering in nanoscale objects. A thermal conduction model for spherical nanoparticles was constructed for non-equilibrium molecular dynamic (NEMD) simulations to investigate variations of the nanoparticle thermal conductivity with particle size. The results show that the nanoparticle thermal conductivity is smaller than the bulk value and that of a thin film with a thickness equal to the particle radius for the same boundary conditions. Another thermal conduction model was constructed to investigate the micro thermal contact resistance variations for various contact scenarios. These results show that the thermal contact resistance is a large part of the conduction resistance that decreases with increasing contact area and increases with increasing contact layer thickness.

Smart fibers for energy conversion and storage

Chemical Society Reviews (2021)

Wujun Ma Yang Zhang Shaowu Pan Yanhua Cheng Ziyu Shao

Fibers have played a critical role in the long history of human development. They are the basic building blocks of textiles. Synthetic fibers not only make clothes stronger and more durable, but are also customizable and cheaper. The growth of miniature and wearable electronics has promoted the development of smart and multifunctional fibers. Particularly, the incorporation of functional semiconductors and electroactive materials in fibers has opened up the field of fiber electronics. The energy supply system is the key branch for fiber electronics. Herein, after a brief introduction on the history of smart and functional fibers, we review the current state of advanced functional fibers for their application in energy conversion and storage, focusing on nanogenerators, solar cells, supercapacitors and batteries. Subsequently, the importance of the integration of fiber-shaped energy conversion and storage devices via smart structure design is discussed. Finally, the challenges and future direction in this field are highlighted. Through this review, we hope to inspire scientists with different research backgrounds to enter this multi-disciplinary field to promote its prosperity and development and usher in a truly new era of smart fibers.

Optimizing Sustainability in Textile Recycling: Life Cycle Assessment of Recycled Polyester Staple Fibers with a Focus on Carbon Emissions, Energy Efficiency, and Water Conservation

ACS Sustainable Chemistry & Engineering (2024)

Deli Li Feng Shi Jing Tao Senlong Yu Yujing He

In addressing the pressing challenges of global climate change and resource scarcity, textile recycling is poised to become a crucial direction for future industrial development. Herein, the raw material sources, production processes, and product attributes of recycled polyester are comprehensively considered based on the product life cycle assessment (LCA) methodologies and the allocation principles outlined in international standards ISO 14040/14044. It establishes carbon emission allocation factors and computational models tailored to real-world production contexts. The global warming potential (GWP), primary energy demand (PED), and water usage (WU) of polyester staple fibers (PSFs) and recycled polyester staple fibers (RPSFs) (produced via bottle flake spinning and popcorn spinning) in mainland China in 2021 were compared. The findings of this study reveal that RPSF possesses notable advantages in mitigating carbon emissions, conserving energy, and reducing water usage. Notably, RPSF produced through the popcorn spinning process demonstrated superior performance, with GWP, PED, and WU being 48%, 46%, and 33% lower, respectively, compared to PSF. The analysis of the LCA of RPSF and the production practices of representative enterprises in China indicates that recycled chemical fibers contribute to fostering green and low-carbon development within the chemical fiber industry.
