“…The emulsions were kept at room temperature for 12 h, then frozen by ice-templating strategy (bottom-up temperature gradient from a mold placed on the top of a copper plate immersed in liquid nitrogen). 33,60 Subsequently, the frozen Pickering emulsions were subjected to freeze-drying (À50 C, 3 days) to obtain the composite aerogels.…”

A facile Pickering emulsion templated approach is used to achieve nanocelluloses (NCs)/poly(aryl ether ketone) (PAEK) composite aerogels with low density and hierarchical porous structure. In this article, we evaluate the factors including water-oil volume ratio, PAEK loading and NCs species to unravel the impact of fiber morphology on the formation and properties of the Pickering emulsions and aerogels. The results show both cellulose nanofibrils (CNF) and microfibrous cellulose (MFC) display excellent performance in stabilizing Pickering emulsions. Besides, the NCs/PAEK composite aerogels reveal a nanonet constructed porous network with excellent properties of thermal insulation. The lowest thermal conductivity of 17.8 mWÁm À1 ÁK À1 is obtained for the CNF/PAEK composite aerogel. To our knowledge, this is one of the most efficient thermal insulators in the reported NCs-based aerogels. Additionally, the NCs/PAEK composite aerogels demonstrate an efficiency of 98.1% in diphenylamine adsorption of water. These findings reveal a potential application of NCs/PAEK composite aerogels in adsorbent and thermal insulators in chemical industries and the construction sector.

“…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”.
