“…Pure PET has weak and strong diffraction peaks at 22.6° and 25.7° respectively, and no strong diffraction peaks near 18°, indicating its amorphous structure. [ 43,44 ] Furthermore, the main diffraction peak of pure PET and KH556@PET situated at 2 θ = 26° and a weak peak at 2 θ = 23° are present and correspond to the lattice plane (100) and (110), respectively. [ 45,46 ] Then, these two diffraction peaks were deconvoluted, as shown in Figure S5 (Supporting Information).…”

High output performance is critical for building triboelectric nanogenerators (TENGs) for future multifunctional applications. Unfortunately, the high triboelectric charge dissipation rate has a significant negative impact on its electrical output performance. Herein, a new tribolayer is designed through introducing self‐assembled molecules with large energy gaps on commercial PET fibric to form carrier deep traps, which improve charge retention while decreasing dissipation rates. The deep trap density of the PET increases by two orders of magnitude, resulting in an 86% reduction in the rate of charge dissipation and a significant increase in the charge density that can be accumulated on tribolayer during physical contact. The key explanation is that increasing the density of deep traps improves the dielectric's ability to store charges, making it more difficult for the triboelectric charges trapped by the tribolayer to escape from the deep traps, lowering the rate of charge dissipation. This TENG has a 1300% increase in output power density as a result of altering the deep trap density, demonstrating a significant improvement. This work describes a simple yet efficient method for building TENGs with ultra‐high electrical output and promotes their practical implementation in the sphere of the Internet of Things.

“…The melting point of r3L is at a temperature of about 160 • C, the known melting point temperature of PP [37]. Several signals were determined for rEL, of which 220 • C is the melting point of PA 6 [38] and 250 • C refers to PET [39]. Furthermore, a lower signal were detected at about 20 to 30 • C, which can be attributed to the presence of elastane [16,40].…”

The production of personal protective equipment (PPE) has increased dramatically in recent years, not only because of the pandemic, but also because of stricter legislation in the field of Employee Protection. The increasing use of PPE, including disposable surgical masks (DSMs), is putting additional pressure on waste collectors. For this reason, it is necessary to find high-quality solutions for this type of waste. Mechanical recycling is still the most common type of recycling, but the recyclates are often classified as low-grade materials. For this reason, a detailed analysis of the recyclates is necessary. These data will help us to improve the properties and find the right end application that will increase the value of the materials. This work represents an extended analysis of the recyclates obtained from DSMs, manufactured from different polymers. Using surface and morphology tests, we have gained insights into the distribution of different polymers in polymer blends and their effects on mechanical and surface properties. It was found that the addition of ear loop material to the PP melt makes the material tougher. In the polymer blends obtained, PP and PA 6 form the surface (affects surface properties), while PU and PET are distributed mainly inside the injection-molded samples.

“…Poly-cotton is a blend of natural cotton (88-94% cellulose) and polyester fibres containing either 65% cotton and 35% polyester or 50/50% mix [16]. Recycling or regeneration of cellulose and polyester from polycotton is one environmentally-friendly and sustainable textile waste management strategy.…”

This research work presents a unique method of making composite from poly-cotton (polyester/cotton blend fabric) directly from hot press machine with controlled parameters: pressure range 0.28-1.4 MPa, temperature 270 o C and time 300s. Cooling rate was neglected while the temperature and time where kept constant. The mechanical strength of the composite was investigated. To achieve this, two samples, the composite and untreated cotton were tested. The tensile stress-strain test was used to determine different targeted properties of the poly-cotton. The mechanical properties of the composite determined include Young modulus, strength and strain. The parameters chosen for the experiment show a positive result, as our experimental results describe a linear relationship between the parameters. Conclusively, the tested recycled poly-cotton composite statistics show a measurable improvement in their properties and can be recommended for re-use in the textiles industries rather than constitutes an environmental nuisance.
