Book Description
The liquid-liquid interface and the two-phase, organic-aqueous systems are a key part of materials science. This book is written both as a state-of-the-art review on the materials synthesised through interfaces and a theoretical introduction on the properties and the fundamentals of the interface. It should be of interest to researchers currently working in various industrial sectors, academia and consultancy.The book deals with newly developed fluorescent polymers, nanoparticle arrays through interfaces and their potential applications in energy storage, enhanced oil recovery and sensors.Chapter 1 provides an overview of interfaces in natural and biological systems. Chapter 2 outlines the fundamental properties of the interface. Chapters 3 and 4 are devoted to the synthesis and self-organisation of nanoparticles and polymers through interfacial systems. The synthesis of conductive, fluorescent and conventional polymers and their properties are extensively covered, with the most important findings from the recent literature highlighted. A deeper analysis on their electronic transport, magnetic and optical properties is beyond the scope of this work and rather an introduction on these properties is presented. Finally, the closing Chapter 5 serves as a discussion and analysis on the potential applications of liquid-liquid boundaries and of the materials synthesised through them.

Book Description
Liquid/liquid interface, either flat or curved, is a unique template for studying self-assembly of a variety of nanomaterials such as nanoparticles and nanorods. The resultant monolayer films can be ordered or disordered depending on the regularity of the nanomaterials. Integration of nanoparticles into two-dimensional structure leads to intriguing collective properties of the nanoparticles. Crystallization can also be guided by liquid/liquid interface. Due to the particular shape of the interface, crystallization can happen in a different manner comparing to the normal solution crystallization. In this dissertation, liquid/liquid interface is employed to guide the crystallization of polymers, mainly focusing on using curved liquid/liquid interface. Due to the unique shape of the interface and feasibility to control the curvature, polymer crystallization can take place in different manner and lead to the formation of curved or vesicular crystals. Curved liquid/liquid interface is typically created through o/w emulsions. With the presence of surfactant, the emulsions are controlled to be stable at least for the polymer crystallization periods. The difference to normal solution crystallization is: the nuclei will diffuse to the curved interface due to the Pickering effect and guide the crystallization along the curved liquid/liquid interface. If the supercooling can be controlled to be very small, crystal growth in the bulk droplets can be avoided. The advantages of this strategy are: 1) the formation process of vesicular type crystals can be monitored by controlling the polymer supply; 2) curved crystals, bowl-like structures and enclosed capsules can be easily obtained comparing to the self-assembly method for vesicle formation; 3) the obtained vesicles will be made of polymer crystals, which will possess the extraordinary mechanical properties. Based on the nucleation type, this dissertation is divided into two parts. The first part is focused on the self-assembly behavior of single-walled carbon nanotubes (SWCNTs) at curved liquid/liquid interface and the crystallization behavior of polymers at curved liquid/liquid interface while SWCNTs in presence. A few crystalline polymers, such as polyethylene (PE), poly(l-lactic acid) (PLLA), and poly(3-hexylthiophene-2,5-diyl) (P3HT), and water/oil systems were used to study the behavior. The formation of nano speckle structure is a crystallization-driven process due to heterogeneous nucleation and crystal growth of polymers at curved liquid/liquid interface. The second part deals with the homogeneous nucleation and crystal growth at curved liquid/liquid interface. Both PE and PLLA were used to conduct the study. For PE, 1,2-dichlorobenzene (DCB), water, and sodium dodecylsulfate (SDS) were used for the emulsion system. The emulsification system for PLLA is p-xylene, water, and hexadecyltrimethylammonium bromide (CTAB). Surfactant concentration can be employed to control the droplet size, thus controlling the final crystal vesicle's size. By controlling the initial polymer concentration, crystal shells with different morphology, such as curved crystal, bowl-like crystals, and crystal vesicles (named lamellaesome) can be obtained. The formation of these unique structures was templated by the curved interface. The formation process and detailed crystal structure are analyzed based on electron diffraction data from different sized lamellaesomes. Mechanical properties of the crystal vesicles and their encapsulation abilities will be discussed. At the end of this dissertation, a summary of my work and future outlook will be given.

Book Description
The history of the liquid-liquid interface on the earth might be as old as that of the liquid. It is plausible that the generation of the primitive cell membrane is responsible for an accidental advent of the oldest liquid interfaces, since various compounds can be concentrated by an adsorption at the interface. The presence of liquid-liquid interface means that real liquids are far from ideal liquids that must be miscible with any kinds of liquids and have no interface. Thus it can be said that the non-ideality of liquids might generate the liquid-liquid interface indeed and that biological systems might be generated from the non-ideal interface. The liquid-liquid interface has been, therefore, studied as a model of biological membrane. From pairing two-phases of gas, liquid and solid, nine different pairs can be obtained, which include three homo-pairs of gas-gas, liquid-liquid and solid-solid pairs. The gas-gas interface, however, is practically no use under the ordinary conditions. Among the interfaces produced by the pairing, the liquid-liquid interface is most slippery and difficult to be studied experimentally in comparison with the gas-liquid and solid-liquid interfaces, as the liquid-liquid interface is flexible, thin and buried between bulk liquid phases. Therefore, in order to study the liquid-liquid interface, the invention of innovative measurement methods has a primary importance.
