Considering the limited supply of fossil fuel, pollution, problems with chemical batteries, and the many potential applications of wearable electronics, the development of more effective lightweight energy sources is important. Piezoelectric nanogenerators (PENGs) can convert a mechanical energy into an electric energy and sometimes may even have the potential to replace conventional chemical batteries. The combination of conventional textiles with PENGs leads to so-called "smart textiles", in other words, textile-based PENGs. More generally, textile-based PENGs can endow conventional textiles with special functionalities such as energy conversion and online health testing (using sensors), while the used conventional textiles can provide platforms for their deployment. This paper reviews the research progress of textile-based PENGs, discusses the classification of piezoelectric materials and electrode materials, and summarizes ways to improve their piezoelectric performance. In addition, several preparation methods of different device structures of textile-based PENGs are compared. Finally, the most important obstacles for the application of textile-based PENGs are addressed at the end of this paper. This compact but relatively comprehensive review will not only aid researchers to better understand textile-based PENGs but also attract the attention of related fields and perhaps inspire more exciting research and progress of wearable textile-based PENGs.

“…This indicates that the PLA open-cell foam exhibits strong oiladsorption ability. It should be pointed out that the above oil-adsorption materials are mostly prepared through phase separation, [41,[52][53][54][55]60] freeze-drying, [59] solution spinning, [56] and surface modification. [57][58][59]61,62] In these preparation processes, toxic organic solvents or chemical reagents are usually used, easily causing secondary environmental pollution and endangering human health.…”

current materials are mostly traditional petroleum-based polymers. [5,6] This will consume petrochemical resources and produce massive hardly degradable waste. [7] Second, toxic organic solvents or flammable foaming agents are widely used in the current preparation processes. [2,3] In addition, the relationship between the foam structure and the oil-adsorption and thermal-insulation performance is still unclear, thus limiting the development of high-performance foams.Poly(lactic acid) (PLA) is one of the biobased and biodegradable polymers with the most potential to replace traditional petroleum-based polymers. [8] Microcellular foaming is a green and safe technology in which supercritical CO 2 or N 2 is used as the physical foaming agent. [9] Therefore, it is an eco-friendly solution to use the microcellular foaming technology to prepare PLA foams for oil-adsorption and thermal-insulation application. Highperformance oil-adsorption materials should have high expansion ratio and open-cell structure, [10] and thermal-insulation materials generally require high expansion ratio and closed-cell structure. [11] However, the preparation of PLA foam with high expansion ratio is still very challenging. [12] The factors affecting the expansion ratio are very complex and can be divided into material structure and process parameters. The material structure mainly includes chain structure, crystalline structure, blend phase structure, etc. [12,13] And the process parameters mainly contain temperature, gas pressure, depressurization rate, etc. [12,14] These factors will affect the gas concentration, polymer viscoelasticity, heterogeneous nucleation, etc.; and then act on the cell nucleation, cell growth and cell stabilization; and finally influence the expansion ratio. [9,12,14] Specially, the PLA is a semi-crystalline polymer with low melt strength and complicated relationship between crystallization and foaming. First, CO 2 can reduce the crystallization and melting temperature of PLA, [9] and change its crystal morphology. [15,16] Meanwhile, crystals in turn can hinder the dissolution of CO 2 in the PLA. [17,18] Second, excessive crystallization will severely limit the cell growth, and ultimately lead to low expansion ratio and non-uniform cell morphology. [17][18][19] Third, the linear PLA generally possesses poor melt strength, which easily leads to cell collapse and gas loss, thereby restricting continuous foam expansion. [12] Fourth, the requirements of high expansion and Bio-based and biodegradable poly(lactic acid) (PLA) foams with a high expansion ratio show great application potential in oil-adsorption and thermal-insulation, which are crucial for oil-spill cleanup and energy saving. However, it is difficult to prepare high-expansion PLA foam due to the poor melt strength and complex crystallization behavior of PLA. Herein, super high-expansion PLA foams with excellent oil-adsorption and thermal-insulation properties are successfully prepared using a modified supercritical CO 2 foaming technology without introducin...

This work aims to optimize the industrial extraction conditions of cellulose microfibers (CMFs) from Washingtonia palm fiber for application in starch bio-composite films. The CMF extraction was a mixed process that combines caustic soda treatment with hydrogen peroxide bleaching in a stirred thermostatic bath. To study the yield, whiteness index and α-cellulose content, three variables were selected; NaOH and H2O2 concentrations and treatment time. The optimum was determined using a Response Surface Methodology (RSM) approach for samples treated for 70 min with 5.21% NaOH and 5.54% H2O2. The optimized CMF was used to produce Starch/CMF bio-composite films with higher mechanical and barrier performance, which increased by 300% and 31%, respectively. Moreover, its moisture absorption and water solubility decreased by about 24% and 26%, respectively after adding 20 wt% CMF. In fact, morphological results showed that the higher CMF in the Starch/CMF20 leads to the heterogeneous CMF distribution and agglomerates resulting in weakened starch films. As a result, the extracted CMF can be a competitive nanofabrication filler.
