The Lagerwall group has most recently published a significantly detailed review on equilibrium and kinetically arrested liquid crystalline structure based on CNC. recently reviewed the phase diagrams of aqueous cellulose nanocrystal (CNC) dispersions and discussed ordered assembly of CNCs in suspensions as well as films. For instance, Gray summarized initial research on the liquid-crystallinity of several cellulose derivatives. There are several excellent reviews on the fundamental science and possible applications of cellulosic liquid-crystals. The creation of functional materials that take advantage of the insights gained in those studies may contribute to expanding the areas in which cellulosics can be used. Numerous fundamental studies on cellulosic liquid crystals have been reported. It is also interesting that the liquid crystal property develops spontaneously. The high stimuli-responsivity and high-order structure of liquid crystals may enable cellulosic functional materials. Liquid crystallinity is one of the characteristic physical properties of cellulosic molecules, although it is not fully employed in the real world. In addition to conventional utilization, developing applications of unused but attractive physicochemical properties of cellulose is important to realize the wealth of a sustainable society because cellulose is reproducible and eco-friendly. Because of its excellent physical properties, including its mechanical and sorption properties, cellulose is widely used in areas such as the manufacture of paper, textiles, and structural components. Thus, this review provides insights into the creation of novel cellulosic ChLC functional materials based on material form designed toward the expanded application of cellulosics.Ĭellulose is the most abundant bioderived organic polymer. Then we comprehensively review research on cellulosic ChLC functional materials in terms of their material forms. We first briefly review the fundamental aspects of cellulosic ChLCs. To date, researchers have reported cellulosic ChLC materials with a wide range of material forms-such as films, gels, mesoporous materials, and emulsions-for diverse functions. The form of such materials is an important factor because material form is closely related with function.

Cellulose derivatives and cellulose nanocrystals exhibit a cholesteric liquid crystal (ChLC) property based on rigidity and chirality, and this property is promising for constructing next-generation functional materials. To further expand the application of cellulose, it is crucial to develop functional materials utilizing cellulosic physicochemical properties that are acknowledged but insufficiently applied. Cellulose is a representative bio-based polymer and has been used in various materials. Wide use of bio-based polymers could play a key role in facilitating a more sustainable society because such polymers are renewable and ecofriendly.
