Polymer future developments

For substrates of WORM and EOD(PCR) disks the industry in the future wants polymers that have a markedly improved resistance to heat softening compared to BPA-PC and, if possible, a lower water absorption and lower birefringence, but otherwise maintain the good characteristics in toughness, production, and cost (194). This goal is being approached in different ways further modification of BPA-PC, newly developed polymers, improvement of the processing characteristics of uv-curable cross-linked polymers, and development of special copolymers and polymer blends, eg,... 

SIMS is one of the most powerful surface and microanalytical techniques for materials characterization. It is primarily used in the analysis of semiconductors, as well as for metallurgical, and geological materials. The advent of a growing number of standards for SIMS has gready enhanced the quantitative accuracy and reliability of the technique in these areas. Future development is expected in the area of small spot analysis, implementation of post-sputtering ionization to SIMS (see the articles on SALI and SNMS), and newer areas of application, such as ceramics, polymers, and biological and pharmaceutical materials. 

Whilst the development of flame retarders has in the past been largely based on a systematic trial-and-error basis, future developments will depend more and more on a fuller understanding of the processes of polymer combustion. This is a complex process but a number of stages are now generally recognised and were discussed in Chapter 5. 

For mechanical wave measurements, notice should be taken of the advances in technology. It is particularly notable that the major advances in materials description have not resulted so much from improved resolution in measurement of displacement and/or time, but in direct measurements of the derivative functions of acceleration, stress rate, and density rate as called for in the theory of structured wave propagation. Future developments, such as can be anticipated with piezoelectric polymers, in which direct measurements are made of rate-of-change of stress or particle velocity should lead to the observation of recognized mechanical effects in more detail, and perhaps the identification of new mechanical phenomena. 

Performance requirements, environmental issues, and avaUabUity/cost of the material will mainly drive material requirement in the future. In order to face the huge tire wastage problem causing major hazards to the environment, future development in mbbery materials will be focused on development of thermoplastic polymer so that used polymer could be recovered by thermal treatment and separation, biological degradation by radiation/addition of chemical into the mbber compound that could be activated by exposure to radiation and development of biopolymer. 

Gazing in the polymer/additive crystal ball appears to indicate that the following future developments affecting polymer/additive analysis will take place ... 

In the development of the discussed fluorinated products a lot of fundamental insight has been gained into permeation and adhesion properties of surface-fluorinated polymers. Although this insight is not discussed in this paper, it may be of interest to mention a few significant fundamental discoveries and also to suggest directions for future development. 

The current European legislative framework relating to the environment is reviewed and a discussion is presented on the effect of this legislation on the ability of the polymer industry, particularly the coatings industry, to meet new requirements. It is concluded that the polymer industry will either have to invest in partnerships with raw material suppliers to obtain novel raw materials or in new process technology and that future developments will probably be incremental, with the emphasis on niche markets. 11 refs. 

Optimization of both resist sensitivity and contrast requires a fundamental appreciation of the radiation chemistry in addition to appreciation how polymer molecular parameters affect the lithographic behavior of the resist. The intent of this chapter is to further the readers understanding of the polymer and radiation chemistry that is associated with a large part of the microelectronics industry, and provide some of the necessary background to effect future developments. 

Liu et al., 2005). Chemical functionalization can improve strength, thermal, electronical properties of polymer/CNT composites and will play a key role in future development and applications of CNT-based nanocomposites. 

Besides the analytical techniques, the theoretical description of polymer brushes allows a deeper understanding of the complex dynamic behavior of polymers on surfaces and is useful for future developments. Here, Roland Netz gives - also for the non-expert - a very helpful theoretical background on the theoretical approaches for the description of neutral and charged polymer brushes. 

Polymer conjugates are most useful in the context of immuno-conjugates. Other protein constructs such as fusion proteins can assist their future development. Soluble polymer con-... 

Biotechnological syntheses of PHB are still in their infancy and some problems may be overcome in near future. However, the synthesis of biodegradable polymers in a catalytic manner offers so many advantages, not only with regards to costs, that future development of such research is worthwhile. 

Each class of sealants has certain attributes inherent to the. polymer on which it is based These attributes often define the sealant s applications and limitations. Future developments are likely to feature the production of more silicone sealants that do not pick up dirt, more latex acrylic sealants that have high performance properties. Urethanes that have improved uv stability, and high performance polysulfides that are made in the United States. 

The book is designed for the reader with some knowledge of polymer science so that familiarity with certain basic concepts is assumed. As the subject is developing so fast, the present monograph can only represent a snapshot of the current state of the art. Nevertheless, it is hoped that it provides a useful reference source and hopefully a discussion of future developments will be incorporated in a subsequent edition. 

The specific constraints and requirements of continuous-flow NMR will be explained in the first chapter, whereas specific applications, such as biomedical and natural product analysis, LC-NMR-MS and LC-NMR in an industrial environment, together with polymer analysis, will be discussed separately. Thus, the reader will obtain a broad overview of the application power of LC-NMR and the benefits of its use. He/She will also be introduced to the pitfalls of this technique. Special attention will be given to the exciting newer coupled techniques such as SFC-NMR and capillary HPLC-NMR. However, new emerging future developments will also be discussed thoroughly.
