Modern technology has enabled the isolation of nanocellulose from plant-based fibers, and the current trend focuses on utilizing nanocellulose in a broad range of sustainable materials applications. Water is generally seen as a detrimental component when in contact with nanocellulose-based materials, just like it is harmful for traditional cellulosic materials such as paper or cardboard. However, water is an integral component in plants, and many applications of nanocellulose already accept the presence of water or make use of it. This review gives a comprehensive account of nanocellulose–water interactions and their repercussions in all key areas of contemporary research: fundamental physical chemistry, chemical modification of nanocellulose, materials applications, and analytical methods to map the water interactions and the effect of water on a nanocellulose matrix.

“…The superhydrophobic PMX was prepared by means of an ice templating method. − As shown in Figure a, a uniform reaction mixture containing the initiator, catalyst, monomers, and MWCNTs was poured into a sealed mold on a pre-cooled plate. Water from the reaction mixture formed ice crystals from bottom to top along with the temperature gradient of the cooled plate and reactive monomers and MWCNTs around the ice crystals due to squeezing by ice crystals.…”

The accumulation of ice in winter has brought many problems in industrial production and everyday life, and how to prevent icing or remove ice rapidly has aroused great attention from researchers in recent years. In this work, we demonstrated a strategy of using a superhydrophobic photothermal and thermal isolation macroporous xerogel (PMX) to delay icing and remove ice efficiently under faint sunlight irradiation. An oriented macroporous xerogel was prepared by an ice templating method, and multi-walled carbon nanotubes acting as the photothermal genesis component under sunlight irradiation were introduced into the xerogel. After fluorination, the PMX presented a robust water repellency and delayed icing. More importantly, numerous macropores in the PMX matrix acted as the thermal barrier that can restrict heat transmission to surroundings at maximum, which guarantees efficient anti-icing and de-icing in low temperature. Water on the PMX surface can never freeze at −30 °C under 0.25 kW/m2 (“0.25 sun”) sunlight irradiation. The outdoor experiment also has confirmed the availability of PMX in a natural winter environment. The PMX integrated with thermogenesis and thermo-isolation functions provides a new route for highly efficient anti-icing and de-icing.

Energy storage plays a vital role in sustainable development. Focus on energy storage using phase change materials (PCMs) are of current research hotspot due to high latent heat value. Nevertheless, poor thermal conductivity, supercooling, phase separation, corrosive nature of salt hydrate is of great concern. Distress related to properties of PCM is resolved using nano additives. Major research focus on the dispersion of nano additive with PCM depends on (a) technique of preparing a novel composite PCM; (b) improvement of their thermophysical characteristic; and (c) advanced application for human comfort without polluting the environment. This article presents a critical review of hybridization techniques of metal, carbon and polymer additives on salt hydrate PCMs. To facilitate researchers, the significant variation on thermophysical properties of salt hydrate with nano additives are vitally compared, analysed and critically reviewed. This review article also includes the advanced application of nano additivesbased salt hydrate PCMs.
