| Abstract | Spinodal decomposition (SD) kinetics in a concentrated polymer solution was investigated with dynamic Monte Carlo simulation. It is found that the positions of scattering peaks are altered during the early stage of phase separation, which cannot be described by the classic Cahn-Hilliard linearized theory quite well, whereas during the late stage SD induced by a deep off-critical quench, the structure factors can be scaled with Furukawa dynamic scaling law associated with a percolation morphology instead of with a non-continuous phase morphology. Our simulation outputs agree basically with the experimental observations in the pertinent literature. It is also revealed that after a deep quench, chain coils shrink strikingly at first and then expand gradually during phase separation. As a consequence, this paper demonstrates that the dynamic Monte Carlo method is unique in detecting both chain configurations and phase separation kinetics and thus very useful for elucidating their relationship in mixtures containing macromolecules. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
