“…35 The limiting area (A lim , extrapolation of the linear part to the x axis) is ∼1.40 nm 2 /molecule, which corresponds to the molecular size of BPOSS-OH in a closely packed state on the water surface. 36 This experimental value is close to that calculated by Materials Studio (MS) software (A BPOSS-OH ≈ 1.54 nm 2 ) (Figure S1). Due to the stiffness of BPOSS-OH, the surface pressure rises sharply in a small region (1.25−1.15 nm 2 /molecule) and the film collapses around 24.1 mN/m.…”

The behavior of giant amphiphilic molecules at the air− water interface has become a subject of concern to researchers. Small changes in the molecular structure can cause obvious differences in the molecular arrangement and interfacial properties of the monolayer. In this study, we have systematically investigated the interfacial behaviors of the giant amphiphilic molecules with different number of hydrophobic BPOSS blocks and one hydrophilic ACPOSS block ((BPOSS) n -ACPOSS (n = 1−5)) at the air−water interface by the surface pressure−area (π−A) isotherm, Brewster angle microscopy (BAM), compression modulus measurement, and hysteresis measurement. We found that both the number of BPOSS blocks and the compression rate can significantly influence the interfacial behaviors of giant molecules. The π−A isotherms of giant molecules (BPOSS) n -ACPOSS (n = 2−5) exhibit a "cusp" phenomenon which can be attributed to the transition from monolayer to multilayer. However, the cusp is dramatically different from the "collapse" of the monolayer studied in other molecular systems, which is highly dependent on the compression rate of the monolayer. In addition, the compression modulus and hysteresis measurements reveal that the number of BPOSS blocks of (BPOSS) n -ACPOSS plays an important role in the static elasticity, stability, and reversibility of the Langmuir films.

“…Additionally, PFPEM presents interesting characteristics such as biocompatibility, biological inertness, and the lack of potential teratogenic and carcinogenic harm to organisms. [23][24][25][26] Therefore, to obtain superhydrophobicity and durability in coating fabrication, POSS incorporated into the PFPEM copolymer via freeradical solution polymerization was designed and synthesized. On the basis of this, a superhydrophobic coating with a high adhesion to glass substrates was prepared.…”

“…As an effective method in creating three-dimensional nanostructures by assembling a two-dimensional molecular layer at the air–water interface, the Langmuir–Blodgett (LB) technique is considered to be the most widely utilized one [ 133 , 134 ]. In the past few years, POSS-based materials have been recognized as promising materials forming stable Langmuir films [ 135 , 136 , 137 , 138 ]. For example, Ishizaki and coworkers prepared a porous SiO 2 nanofilm by using hybrid block copolymers consisting of N-dodecyl acrylamide (DDA) and silsesquioxane (SQ) comonomers (p(DDA/SQ26)- b -pDDA) ( Figure 17 ) [ 77 ].…”

Self-Assembly and Applications of Amphiphilic Hybrid POSS Copolymers

et al. 2018

Understanding the mechanism of molecular self-assembly to form well-organized nanostructures is essential in the field of supramolecular chemistry. Particularly, amphiphilic copolymers incorporated with polyhedral oligomeric silsesquioxanes (POSSs) have been one of the most promising materials in material science, engineering, and biomedical fields. In this review, new ideas and research works which have been carried out over the last several years in this relatively new area with a main focus on their mechanism in self-assembly and applications are discussed. In addition, insights into the unique role of POSSs in synthesis, microphase separation, and confined size were encompassed. Finally, perspectives and challenges related to the further advancement of POSS-based amphiphilics are discussed, followed by the proposed design considerations to address the challenges that we may face in the future.
