“…With the depletion of fossil resources and global catastrophic climate change, biomass resources with renewability, biodegradability, and eco-friendliness have gained extensive attention over the last decade [ 23 , 24 , 25 ]. As the most abundant component in biomass, cellulose is ubiquitous on earth and has been widely transformed into various functional materials and applied in packaging and wrapping [ 26 , 27 , 28 ], fluorescent smart materials [ 29 ], energy storage materials [ 30 , 31 ], and so on. However, high-cost wood pulp and cotton pulp are usually two major sources of cellulose, limiting the development of renewable resources [ 32 , 33 ].…”

Disposable paper cups are usually composed of high-grade paper board and an inner polyethylene coatings and are extensively used in daily life. However, most disposable paper cups are only used for a short time and then incinerated or accumulated in landfill at the end of their service due to the difficulty in separating the components, leading to a serious threat to our ecosystem. Therefore, developing a facile and green method to recycle and reuse disposable paper cups is vital. By using ionic liquid 1-allyl-3-methylimidazolium chloride (AmimCl) as a solvent, transparent and homogenous cellulose/polyethylene composite films were successfully prepared from used bamboo-based disposable paper cups through the “one-pot method”, without any pre-treatment. It was found that there was a transformation of cellulose I to II after the dissolution and regeneration processes, and the crystallinity degree of the regenerated cellulose-based materials decreased significantly, resulting in a change in thermal properties. Meanwhile, compared to traditional pure cellulose films, the composite films possessed good UV-shielding properties and hydrophobicity. Moreover, they also displayed good mechanical properties. Additionally, the size of the ground PE coatings displayed obvious effects on the structures and properties of the composite films, where the CPE100 (sieved with 100–200 mesh) possessed the most homogeneous texture and the highest tensile strength (82 Mpa), higher than that of commercial polyethylene film (9–12 MPa), showing superiority as packaging or wrapping materials. Consequently, the goals to fabricate uniform cellulose/polyethylene composite films and valorize the solid waste from disposable paper cups were simultaneously achieved by a facile and green “one-pot method”.

“…Mao et al [22] found that for the SAT composited with 2 wt% PAM and 5.4 wt% Na 2 B 4 O 7 ⋅ 10H 2 O, the supercooling degree was 4 K, and the phase change temperature was 52 °C; after using Na 3 PO 4 ⋅ 12H 2 O as the nucleating agent for the SAT/3.3 wt% PAM composite, Na 3 PO 4 ⋅ 12H 2 O could inhibit supercooling and reduce the supercooling degree to 4 K. In addition to hydrated salt nucleating agents, commonly used nanonucleating agents for SAT include nanocopper, [23] silver nitride nanoparticles, [24] silver nanoparticles, [25] nanozirconia, [26] nano-chitin whiskers, [27] cellulose nanofibril suspension and nano-silicon nitride. [28,29] Many researchers have studied the addition of porous substrates to SAT composite PCMs. Mao et al [30] prepared SAT/ carboxylmethyl cellulose (CMC)/DHPD/expanded graphite composites by melt blending and tested its thermal properties.…”

A thickener that could address the phase separation problems of sodium acetate trihydrate (SAT) was determined by the gravity sedimentation method. Additionally, a hydrated salt nucleating agent to effectively reduce the supercooling of SAT was sought using the step‐cooling method. Combining these findings, a new SAT composite phase change material (SAT CPCM) was prepared. Additionally, a sample containing expanded graphite (EG) was prepared by melt blending to enhance the thermal conductivity. Our results show that a sample prepared with 1.5 % xanthan gum and 2 % sodium pyrophosphate decahydrate as a hydrated salt nucleating agent basically eliminates supercooling, its thermostability better than that of the composite phase change material using disodium hydrogen phosphate dodecahydrate. A sample with 6 % EG stays molten without leakage at a higher temperature and in the cooling test, the material‘s supercooling degree was only 1.1 °C. After 200 cooling‐heating cycles, the thermal stability was good, with high latent heats of 230.52 kJ/kg and thermal conductivities of 1.789 W(m ⋅ K) −1. This composite phase change material has great application potential in the field of low‐temperature heat storage.
