The synthesis and use of polymer cubosomes have received significant attention in recent years. Polymer cubosomes are highly stable colloidal particles with triply periodic minimal surface. Inherently, polymer cubosomes have several advantages over other nanostructures like micelles and vesicles as they are quite uniform and porous structures. Due to the large specific surface area of the interior and bicontinuous nature, they have the capacity to load significant amounts of hydrophobic and hydrophilic substances. Additionally, their properties make them suitable for use as nanotemplates, catalyst supports, and nanovehicles for the separation and regulated release of biomolecules. Regarding their synthesis, block copolymers that may form cubosomes are still few in number, in part because different block copolymers require various self‐assembly conditions. In order to create polymer cubosomes, five different self‐assembly techniques have been reported, including the co‐solvent method, flash nanoprecipitation, evaporation‐induced self‐assembly, solvent‐diffusion‐evaporation‐mediated self‐assembly, and polymerization‐induced self‐assembly. This review article describes various synthetic techniques for creating polymer cubosomes and goes into further depth on recent uses for polymer cubosomes. It is anticipated that this article may offer some helpful guidance to researchers interested in the different applications of polymer cubosomes.

“…This work is the only report of inverse bicontinuous structures formed by solution self‐assembly of LC BCPs to date, and the initial concentration of BCPs could up to 5 wt% because of the highly asymmetric molecular structures. Subsequent research showed that inverse bicontinuous structures could be obtained at lower hydrophilic/hydrophobic ratio by raising the temperature 88 …”

Anisotropic polymeric nanoparticles (NPs) have attracted considerable attention due to their morphology-dependent applications in the fields of nanocatalysts, drug delivery and sensors. By introducing liquid crystalline (LC) driving force into NPs, the region of non-spherical shapes in phase diagrams can be broadened effectively, which attracts great interest of many researchers. LC mesogens can be easily introduced to monomers, such as acrylates and methacrylates, as side groups connected by spacers with tunable length, and then side-chain LC polymers can be acquired after polymerization accordingly. Among these polymers, amphiphilic block copolymers (BCPs) have been widely studied, attributed to their property of spontaneous assembly into NPs under appropriate conditions. In this review, based on traditional solution self-assembly and polymerization-induced self-assembly, the recent research into side-chain LC BCP NPs is elaborated in terms of the aspects of the types of LC mesogens, LC phases, morphologies and functionalities. Finally, we summarize recent progress, and prospect the development trend in the future.

“…It was then extended for ABCs as well, for ABCs with P < 1/2 forming spherical micelles and worms, and for the ones with 1/2 < P ≤ 1 forming vesicles and lamellae (Figure c) . It has been recently reported that ABCs also possess the capability to self-assemble into complex and highly ordered inverse structures, such as inverse bicontinuous cubic mesophases (polymer cubosomes) in solution − in an analogous fashion to lipids with P > 1. , The block copolymer based cubosomes are colloidal particles exhibiting an internal inverse cubic structure with the polymer layer draped over infinite periodic minimal surfaces and two continuous interpenetrating channels . Some pioneering work has demonstrated that polymer cubosomes exhibit high loading capacity and sustained release behavior with potential applications in biomedicine , and templating. − In spite of these previous elegant studies, the primary method for preparing polymer cubosomes is still time-consuming and inefficient solution self-assembly processes, which limit the amount of the product due to its dilute condition. , The scalable preparation of polymer colloidal particles containing highly ordered inverse mesophases is highly desirable, and yet it remains a challenge.…”

Triggered Degradable Colloidal Particles with Ordered Inverse Bicontinuous Cubic and Hexagonal Mesophases

We herein report a facile strategy to prepare triggered degradable block copolymer nano/macro-objects, ranging from typical micelles, worms, jellyfish, and vesicles to rarely achieved spongosomes, cubosomes, and hexosomes via RAFT-mediated polymerizationinduced self-assembly (PISA). The morphological transitions from a simple spherical micelle to a spongosome, ordered Im ̅ 3m cubosome, and p6mm hexosome were captured and demonstrated by TEM, SEM, and synchrotron SAXS. In addition, morphological phase diagrams including important factors, such as solid contents, degree of polymerization (DP), and stabilizer block chain length, were constructed to unveil the formation mechanism and guide the scalable preparation of complex morphologies with packing parameter (P) > 1. This study not only represents an example that achieved inverse mesophases via acrylate-based monomers with high conversion but also reports a triggered degradable system in the most extended morphological range via PISA. The facile synthesis and stimuli-responsiveness of our system should greatly expand the utility of polymer inverse mesophases for triggered releasing, templating, and many other applications.
