A Concise Introduction to Polymer Physics

Release Date: 2025-07-05
This textbook provides a concise and transparently structured one-semester course in polymer physics - the science, in addition to polymer chemistry, behind a class of ubiquitous materials. It covers all major theoretical concepts and their applications in six chapters, including the conformations of chains, the thermodynamics of mixtures, solutions and networks, and the dynamics of polymers. Selected topics highlight aspects of polymer mechanics, the role of particulate fillers, stable and labile liquid crystal polymers, and polyelectrolytes. Solved problems deepen and extend important points that are explained in the main chapters. The emphasis is on the derivation of the results and not on their mere presentation. If a result can be obtained using different theoretical methods or viewed from a different angle, an attempt is made to explain the relationships between the methods as clearly as possible. In addition, the validation of theoretical results through suitable experiments is always included. All this assumes a certain familiarity with statistical thermodynamics and its mathematics, which means that the text is best suited for upper undergraduate level.

The science of mathematical modelling and numerical simulation is generally accepted as the third mode of scienti?c discovery (with the other two modes being experiment and analysis), making this ?eld an integral component of c- ting edge scienti?c and industrial research in most domains. This is especially so in advanced biomaterials such as polymeric hydrogels responsive to biostimuli for a wide range of potential BioMEMS applications, where multiphysics and mul- phase are common requirements. These environmental stimuli-responsive hydrogels are often known as smart hydrogels. In the published studies on the smart or stimu- responsive hydrogels, the literature search clearly indicates that the vast majority are experimental based. In particular, although there are a few published books on the smart hydrogels, none is involved in the modelling of smart hydrogels. For the few published journal papers that conducted mathematical modelling and numerical simulation, results were far from satisfactory, and showed signi?cant d- crepancies when compared with existing experimental data. This has resulted in ad hoc studies of these hydrogel materials mainly conducted by trial and error. This is a very time-consuming and inef?cient process, and certain aspects of fun- mental knowledge are often missed or overlooked, resulting in off-tangent research directions.
Liquid Crystalline and Mesomorphic Polymers

Among the various new directions in modern polymer science, the design and investigation of liquid crystal (LC) polymers have been the ones growing most actively and fruitfully. In spite of that, the possible formation of an anisotropic LC phase was only demonstrated theoretically for the first time in the 1950s by Onsager [1] and Flory [2], and then experimentally verified in the studies with polypeptides solutions. In essence, the studies of these LC lyotropic systems did not deviate from the theme of purely academic interest. It was at the beginning of the 1970s that the experimental "explosion" occurred, when aromatic polyamides were synthesized and their ability to form LC solutions in certain very aggressive solvents was discovered. The search for practical applications of such LC systems was crowned with the successful creation of the new generation of ultrastrong high-modulus ther mostable fibers, such as the Kevlar, due to the high degree of order of the macromolecules in the anisotropic LC state. In fact, these investigations coincided with the swift emergence on the practical "scene" of thermotropic low-molar-mass liquid crystals, with the use of these materials in microelectronics and electro optics (figures and let ters indicators, displays in personal computers, and flat TV, etc.). Polymer scientists also began to develop methods of synthesizing thermotropic LC polymers by incorporating mesogenic fragments in the main (main-chain LC polymers) or side branchings of the macromolecules (side-chain or comb shaped polymers).
