“…[ 4–10 ] The literature related to nanocelluloses grows rapidly, where nanocellulose based nanocomposites, films and fibers, structural colors, barrier properties, emulsions, and viscosity tunings have been among the focal areas in science and technology, already reviewed extensively. [ 7–18 ] Moreover, in wood‐based bulk materials, new directions have been taken, for example, combining strength and toughness, as recently reviewed. [ 16 ]…”

Nanocellulose: Recent Fundamental Advances and Emerging Biological and Biomimicking Applications

In the effort toward sustainable advanced functional materials, nanocelluloses have attracted extensive recent attention. Nanocelluloses range from rod‐like highly crystalline cellulose nanocrystals to longer and more entangled cellulose nanofibers, earlier denoted also as microfibrillated celluloses and bacterial cellulose. In recent years, they have spurred research toward a wide range of applications, ranging from nanocomposites, viscosity modifiers, films, barrier layers, fibers, structural color, gels, aerogels and foams, and energy applications, until filtering membranes, to name a few. Still, nanocelluloses continue to show surprisingly high challenges to master their interactions and tailorability to allow well‐controlled assemblies for functional materials. Rather than trying to review the already extensive nanocellulose literature at large, here selected aspects of the recent progress are the focus. Water interactions, which are central for processing for the functional properties, are discussed first. Then advanced hybrid gels toward (multi)stimuli responses, shape‐memory materials, self‐healing, adhesion and gluing, biological scaffolding, and forensic applications are discussed. Finally, composite fibers are discussed, as well as nanocellulose as a strategy for improvement of photosynthesis‐based chemicals production. In summary, selected perspectives toward new directions for sustainable high‐tech functional materials science based on nanocelluloses are described.

“…It has been demonstrated by many researchers that nanocellulose can be responsive to temperature, pH and mechanical changes that are useful in biomedical and environmental applications. 277 The abundance of hydroxyl groups along the backbone of nanocellulose enables the ease of functionalizing hydrophobic group, or introduction of ionic and π-π stacking system for various usage. With the advancing technology, 4D printing is believed to promote the rapid manufacturing of products with good quality and real usability if it is able to realize an integrative creation of an intelligent and autonomous process to eliminate the need for post-printing treatment.…”

“…Furthermore, nanoencapsulated particles exhibit exceptional colloidal stability, indicating their potential for use as nanocarriers for thermosensitive drug delivery in biomedical applications [ 36 , 37 , 38 , 39 , 40 ]. In addition, the solution processability of colloidally stable PCMs offers low cost and facile integration of PCMs into stimuli-responsive nanocomposites [ 41 , 42 , 43 , 44 ].…”

Sub-100-nm Nearly Monodisperse n-Paraffin/PMMA Phase Change Nanobeads

et al. 2021

In this study, we demonstrate the colloidal synthesis of nearly monodisperse, sub-100-nm phase change material (PCM) nanobeads with an organic n-paraffin core and poly(methylmethacrylate) (PMMA) shell. PCM nanobeads are synthesized via emulsion polymerization using ammonium persulfate as an initiator and sodium dodecylbenzenesulfonate as a surfactant. The highly uniform n-paraffin/PMMA PCM nanobeads are sub-100 nm in size and exhibit superior colloidal stability. Furthermore, the n-paraffin/PMMA PCM nanobeads exhibit reversible phase transition behaviors during the n-paraffin melting and solidification processes. During the solidification process, multiple peaks with relatively reduced phase change temperatures are observed, which are related to the phase transition of n-paraffin in the confined structure of the PMMA nanobeads. The phase change temperatures are further tailored by changing the carbon length of n-paraffin while maintaining the size uniformity of the PCM nanobeads. Sub-100-nm-sized and nearly monodisperse PCM nanobeads can be potentially utilized in thermal energy storage and drug delivery because of their high colloidal stability and solution processability.
