“…Among them, the mixed aerogel exhibits a high transmissivity of >80% in visible light, and the CNCs aerogel exhibits a high transmissivity of >90% in visible light. These values are higher than those of the reported bagasse aerogels and comparable to those of silica aerogels, ,,− probably because the dispersed sugarcane CNCs have a weaker visible-light scattering effect than the dispersed sugarcane CNFs, which can be verified in the spectral diagram of the solution prepared using sugarcane cellulose (Figure a). Therefore, the optical properties of bagasse aerogels can be reasonably adjusted by changing the aspect ratio of cellulose in the gel network.…”

The preparation of functional composite aerogels for building envelopes, especially for building glazing as the key climate moderator, has been widely investigated to improve the sustainability of buildings. Unfortunately, the prohibitive costs, mechanical brittleness, and optical opacity limit the current development and application of composite aerogels. Herein, using the controllable extraction of cellulose from bagasse, a low-cost (less than $3 per square foot), flexible (>15% elastic deformation under 0.02 MPa) bagasse aerogel film with high visible-light transparency (>80% transmittance of visible light) and superinsulation (0.0158 W m–1 K–1) was developed. These properties were achieved by constructing a uniform three-dimensional network structure using elastic polysiloxane and a mixture of cellulose nanofibers and cellulose nanocrystals in an equal proportion. This cellulosic aerogel film would have the latent potential of application in highly glazed modern buildings to reduce the energy loss from windows.

“…The as-obtained aerogels exhibit excellent oil absorption capability. Similarly, in order to preserve the hierarchically arranged pore structures directionally within natural sugarcane, 332,333 Chen et al 75 reported the fabrication of aerogels through a similar top-down approach. The TEMPO/NaClO/NaClO 2 mixture was applied to remove the lignin in the sugarcane under appropriate conditions.…”

“…Besides the well-known balsa wood, many innovative works have been reported based on multifarious plants in recent years, such as sugarcane, rattan, corn stack and so on. [74][75][76][77] For example, Peng et al reported corn stalk pith/hexamethyldisilazane BAs (CSP/HMDS-BAs) with directional channel structures, similar to those found in natural wood-based aerogels. 74 The CSP was mixed uniformly in a deep eutectic solvent (DES) system, followed by TEMPO/ NaClO/NaClO 2 oxidization, microfibrillation, and hydrophobic treatment (Fig.…”

The demand for sustainable, low-cost, and high-performance natural cellulose foams with isotropic structures has increased greatly due to growing environmental awareness. However, the synthesis of current cellulose foams/aerogels requires substantial amounts of energy and chemicals, mainly due to the challenges posed by the poor solubility and processability of raw cellulose derived from biomass resources. Consequently, these challenges further highlight the advantages offered by the direct utilization of natural cellulose foams, considering their economic and environmental benefits. Previous studies on natural cellulose foams have predominantly focused on specific plant components such as phloem, xylem, vascular vessels, fruits, and seeds. In this study, we present an overlooked alternative: the aerenchyma tissue of aquatic or wetland plants. Specifically, we investigated on Juncus effusus L. (JE), a commonly found problematic wetland weed that is known for its high reproductive ability, causing a reduction in annual forage yield. The aerenchyma tissue of JE was discovered to possess a well-developed 3D interconnected hierarchical structure, exhibiting remarkable properties as a natural lignocellulosic foam. These properties include exceptional compressibility, hydrophobicity (water contact angle: 147°), lightweights (density: 0.017 g/cm3), and high porosity (98%). Through this study, we have introduced a novel natural cellulose foam and explored the utilization of biomass derived from wetland weed wastes.
