“…Foam is generally prepared by dispersing gases into a liquid, solid or hydrogel using various approaches such as freeze-drying, supercritical drying, oven drying and melt-processing, and porous foam materials have a wide range of applications such as packaging, absorption and tissue engineering owing to light weight, low density and heat and sound insulation [40,[46][47][48]. Due to superior mechanical performances and size in the nanoscale, nanocellulose has attracted more attention as reinforcement to improve mechanical properties of petroleum and bio-based polymer foams such as polyurethane (PU), poly(vinyl alcohol) (PVA), poly(lactic acid) (PLA), tannin and xylan [48][49][50][51][52][53][54][55][56][57][58][59][60][61].…”

“…When the density is taken into account, the specific Young's modulus of the crystalline cellulose is significantly higher than that of glass fibers, aluminium and steel, as shown in Table 1. Over the past few years, a large number of review articles have been published in many aspects of nanocellulose, including nanocellulose production, characterization, modification and applications [5,21,[32][33][34][35][36][37][38][39][40][41][42][43]. However, the use of plant-derived nanocellulose in polymeric porous materials has not been addressed enough.…”

“…For the drug delivery field, carrier morphology, especially the porosity structure, controls the drug adsorption and release since the drug will pass through the internal pore to be retained inside and release outside regardless of the chemistry interaction. Sun et al [ 186 ] underlined that the critical factor in controlling and modulating the pore structure of ultralightweight porous materials is selecting a drying method [ 186 ]. Initially, freeze-drying, supercritical drying, and evaporation drying have been utilized in fabricating ultralightweight porous materials.…”

The ‘Back-to-nature’ concept has currently been adopted intensively in various industries, especially the pharmaceutical industry. In the past few decades, the overuse of synthetic chemicals has caused severe damage to the environment and ecosystem. One class of natural materials developed to substitute artificial chemicals in the pharmaceutical industries is the natural polymers, including cellulose and its derivatives. The development of nanocelluloses as nanocarriers in drug delivery systems has reached an advanced stage. Cellulose nanofiber (CNF), nanocrystal cellulose (NCC), and bacterial nanocellulose (BC) are the most common nanocellulose used as nanocarriers in drug delivery systems. Modification and functionalization using various processes and chemicals have been carried out to increase the adsorption and drug delivery performance of nanocellulose. Nanocellulose may be attached to the drug by physical interaction or chemical functionalization for covalent drug binding. Current development of nanocarrier formulations such as surfactant nanocellulose, ultra-lightweight porous materials, hydrogel, polyelectrolytes, and inorganic hybridizations has advanced to enable the construction of stimuli-responsive and specific recognition characteristics. Thus, an opportunity has emerged to develop a new generation of nanocellulose-based carriers that can modulate the drug conveyance for diverse drug characteristics. This review provides insights into selecting appropriate nanocellulose-based hybrid materials and the available modification routes to achieve satisfactory carrier performance and briefly discusses the essential criteria to achieve high-quality nanocellulose.

“…For excellent compression space and mechanical behavior, cellulose in aerogels is generally annealed into carbon materials. Continuous porous structure of the aerogels is not only kept, but also the ber diameter and the density of ber entanglement points reduce which cause the decreased density and the increased compression space of the aerogel (Huang et al 2021b;Sun et al 2021a). Thus, GWA is annealed to the carbonized graphene coated waste paper aerogel (C-GWA) in a nitrogen atmosphere at 500°C to realize the characteristics of light weight and high compression.…”

Graphene is complexed with cellulose fibers to construct 3D aerogels, which is generally considered to be an environmentally friendly and simple strategy to achieve wide sensing, high sensitivity and low detection of wearable piezoresistive pressure sensors. Here, graphene is incorporated into waste paper fibers with cellulose as the main component to prepare graphene coated waste paper aerogel (GWA) using a simple “filtration-oven drying” method under atmospheric pressure. The GWA was further annealed to obtain the carbonized graphene coated waste paper aerogel (C-GWA) to achieve low density and excellent resilience. The result shows that the C-GWA has a rough outer surface due to the 3D structure formed by interpenetrated fibers and the carbon skeleton with wrinkles. The sensor based on GCA shows low density (25mg/cm3), a wide detection range of 0-132 kPa, an ultra-low detection limit of 2.5 Pa (a green bean, ≈ 53.4 mg), and a high sensitivity of 31.6 kPa− 1. In addition, the sensor based on C-GWA with the excellent performance can be used to detect human motions including the pulse of the human body, cheek blowing and bending of human joints. The result indicates that the sensor based on C-GWA shows great potential for wearable electronic products.
