Confined self-assembly of cellulose nanocrystals in a shrinking droplet.
We have studied how cellulose nanocrystals (CNC) self-assemble into liquid crystalline phases in shrinking, isolated droplets. By adjusting the water dissolution rate of an aqueous CNC droplet immersed in a binary toluene-ethanol mixture we can control the final morphology of the consolidated microbead. At low ethanol concentration in the surrounding fluid dense microbeads of spherical morpholo...
متن کاملHierarchical Self-Assembly of Cellulose Nanocrystals in a Confined Geometry
Complex hierarchical architectures are ubiquitous in nature. By designing and controlling the interaction between elementary building blocks, nature is able to optimize a large variety of materials with multiple functionalities. Such control is, however, extremely challenging in man-made materials, due to the difficulties in controlling their interaction at different length scales simultaneousl...
متن کاملCellulose nanocrystals: chemistry, self-assembly, and applications.
Cellulose constitutes the most abundant renewable polymer resource available today. As a chemical raw material, it is generally well-known that it has been used in the form of fibers or derivatives for nearly 150 years for a wide spectrum of products and materials in daily life. What has not been known until relatively recently is that when cellulose fibers are subjected to acid hydrolysis, the...
متن کاملTwo-dimensional self-assembly of amphiphilic porphyrins on a dynamically shrinking droplet surface.
Developing a new field of molecular self-assembly in the sub-micrometer regime-with precision as high as that used to make discrete nano-sized molecular architectures through molecular design-is a major challenge for supramolecular chemistry. At present, however, there is no effective strategy for controlling the assembling molecules when their quantity is greater than one thousand. Herein, we ...
متن کاملSurface-Confined Molecular Self-Assembly
The design and fabrication of nanometer-sized entities of defined structure on the nanometer scale is a challenge hardly achievable by large-scale top-down procedures. In particular, alternative techniques are needed to structure surfaces at very small length scales. In nanotechnology the process of self-assembly has become a potent method which allows to vanquish these difficulties. Self-assem...
