Potential applications polymer science

The nanometer level of characterization is necessary for nanochemistry. We have learned from the history of once-new disciplines such as polymer science that progress in synthesis (production method) and in physical and chemical characterization methods are essential to establish a new chemistry. They should be made simultaneously by exchanging developments in the two areas. Surface forces measurement is certainly unique and powerful and will make a great contribution to nanochemistry, especially as a technique for the characterization of solid-liquid interfaces, though its potential has not yet been fully exploited. Another important application of measurement in nanochemistry should be the characterization of liquids confined in a nanometer-level gap between two solid surfaces, for which this review cites only Refs. 42-43. 

Thus, fundamentally the interest is in testing the limits and theory of polymer behavior in end-tethered systems, e.g., viscoelastic behavior, wetting and surface energies, adhesion, shear forces relevant to tribology, etc. It should be noted that relevant surfaces and interfaces can also refer to polymers adsorbed in liquid-liquid, liquid-gas, solid-gas, and solid-liquid interfaces, which makes these polymer systems also of prime importance in interfacial science and colloidal phenomena (Fig. 2). Correspondingly, a wide number of potential applications can be enumerated ranging from lubrication and microelectronics to bioimplant surfaces. 

It should be stressed that in almost all applications of isotopic methods in polymer science, they should be used to supplement other techniques only in this way, can their full potentialities be realised. 

The synthesis of optically active polymers is an important area in macromolecular science, as they have a wide variety of potential applications, including the preparation of CSPs [31-37]. Many of the optically active polymers with or without binding to silica gel were used as CSPs and commercialized [38]. These synthetic polymers are classified into three groups according to the methods of polymerization (1) addition polymers, including vinyl, aldehyde, isocyanide, and acetylene polymers, (2) condensation polymers consisting of polyamides and polyurethanes, and (3) cross-linked gels (template polymerization). The art of the chiral resolution on these polymer-based CSPs is described herein. 

The third International Dendrimer Symposium took place at Berlin Technical University in 2003. Interdisciplinary lectures demonstrated the extent to which dendritic molecules branch ouf into other areas of science, such as physics, biology, medicine, and engineering. The possibilities of functionalisation and resulting applications in industry were at the focus of this symposium. For example, nano-dimensioned dendrimer-based contrast agents were presented as multilabels for visualisation of blood vessels (see Chapter 8). Potential applications of dendritic materials as luminescence markers in diagnostics attracted lively interest (see Chapter 8). Consideration of the differences between dendrimers and hyperbranched polymers from the viewpoint of their cost-favourable application was also a topic of discussion [18]. 

These excited-state electron transfer reactions were mainly investigated using time-resolved spectroscopic techniques such as flash photolysis and flash fluorescence. The extensive work on the photochemistry of MLCT excited states is motivated by both the interest in basic science and the potential applications to many areas of chemistry, for example, biochemistry, solar energy, and conducting polymers.130 135... 

Although a wide range of polymers have been investigated with various cyclodex-trins, these studies mainly focused on the IC preparation techniques and characterization of solid phases. The solution properties, such as the self - assembly behavior, dissociation, particle size an surface activity, were not commonly reported. These solution properties, especially the assembly and surface behavior, are vital for the potential applications of such systems in biomedical science, such as in controlled drug delivery. 

In this review, the problems of complex formation in different systems of interacting macromolecules namely in polymer-polymer, polymer-alternating or statistical copolymer systems are discussed. The influence of solvent nature, the critical phenomena, equilibrium, selectivity and co-operativity in reactions are considered. The perspectives of development of this field of polymer science and the potential practical applications of interpolymer complexes are pointed out. 

This movement is a key challenge for the entire field of advanced materials, but it is a particularly exciting challenge for silicon-based polymers. From the point of view of materials, silicon-based polymers span the three traditional domains plastics, ceramics, and metals. Potential applications are equally diverse. Silicon-based polymers range from structural materials, to optoelectronic devices, and to speciality materials for biomedical applications. We are in a unique position to capture the benefits of this merger of materials and polymer science. 

High energy radiation exists under many forms, but the most important types for the potential applications they have in polymer science and technology are X-rays and gamma rays on the one hand, and accelerated electrons on the other. The recent development of swift ion beam accelerators that induce reactions exhibiting some common features with widespread radiation treatments cited at first will be also accounted for. 

In summary, recent advances in aqueous catalytic polymerizations have afforded a range of new materials, particularly polymer latexes previously inaccessible and new water-soluble polymers. Various attractive topics for fundamental research have in turn emerged, and potential applications can be envisioned. The attractiveness and versa ii lily of fhis field results from fhe overlap and combination of polymer chemistry, organometalhc chemistry, catalysis, and colloid science.
