Traditional engineering textbooks are substantially limited by approaches relying on analytical solutions where most of the applications are described by differential equations without simple analytical solutions. An alternative is to design a textbook around computer-program-based simulations, where the simulations progressively evolve through the textbook with the complexity of the content. Simulations can solve more complex problems with immediate utility in practical applications, and these capabilities are able to achieve higher levels of Bloom’s Taxonomy with quiz-based methods that can be performed in a few minutes. By example, the polymer engineering topic of thermoset polymerization has a global market of tens of billions of dollars; yet, the textbook coverage of the subject is sparse due to the inability of simple analytical solutions to provide useful solutions to practical applications. This paper provides a foundation and approach for a simulation-based-learning textbook to cover the important topic of polymer engineering which will also bridge the gap between student and researcher. A questionnaire was passed to two groups of college students to identify their response to the simulation-based learning of the subject of polymer engineering. The majority of students recommended this method.

“…Many researchers report that isocyanate addition to alcohols might involve complex mechanisms, which would be difficult to interpret in kinetic models even for linear PUR. [2][3][4] Various uncertainties make it problematic to derive reaction rate constants for every step of the mechanism even for monofunctional alcohols. Higher homologs, such as diisocyanates and macrodiols would result in further complexity, because of several NCO groups, which would react with several OH functionalities.…”

The research provides a concise overview of numerous biomedical and biomechanics uses for polymer-based materials in medical applications. Polymer-based materials are used to repair or enhance the functionality of tissues or organs damaged or disjointed in the context of implants and medical equipment, thereby enhancing patients’ well-being. The critical criterion for selecting the biomaterial is its appropriateness to the body. Polymer-based material must have certain essential characteristics to enable lengthy-term use. This family of materials, which may execute stimuli-induced active motions, includes shape-changing and shape-memory polymers as examples. Significant interest in the area of biomedicine has developed for these materials over the last 20 years, especially in minimally invasive surgeries. In this regard, the development of novel antimicrobial technologies for biomedical implementations depends heavily on polymeric biomaterials and would continue to do so. This review article focuses on the properties and applications of smart polymers application, biomolecule conjugates of smart polymers on surfaces, and Forms of smart polymeric biomaterials. This article presents an overview of the scope of application of the three polymeric-based materials.
