Journal ArticleDOI
Untangling the Effects of Chain Rigidity on the Structure and Dynamics of Strongly Adsorbed Polymer Melts
Jan-Michael Y. Carrillo,Shiwang Cheng,Rajeev Kumar,Monojoy Goswami,Alexei P. Sokolov,Bobby G. Sumpter +5 more
TL;DR: In this article, a detailed analysis of coarse-grained molecular dynamics simulations of semi-lexible polymer melts in contact with a strongly adsorbing substrate is presented, where the segments in the interfacial layer are characterized by counting the number of trains, loops, tails, and unadsorbed segments.
Journal ArticleDOI
Morphologies of block copolymers composed of charged and neutral blocks
TL;DR: In this article, a comprehensive picture is beginning to emerge on the fundamental role of electrostatics in the micro-phase separation of charged block copolymers, which can be used to direct targeted structures that endow the materials with desired properties that can have tremendous potential in technological applications.
Journal ArticleDOI
Effects of backbone rigidity on the local structure and dynamics in polymer melts and glasses
Rajeev Kumar,Monojoy Goswami,Bobby G. Sumpter,V. N. Novikov,V. N. Novikov,Alexei P. Sokolov,Alexei P. Sokolov +6 more
TL;DR: This work demonstrates that the rigid polymer chains have higher averaged Voronoi polyhedral volumes and significantly wider distribution of the volume due to frustration in the chain packing and discusses the advantage of the rigid polymers for possible enhancement of transport properties, e.g. for enhancing ionic conductivity in solid polymer electrolytes.
Journal ArticleDOI
New insights into the dynamics and morphology of P3HT:PCBM active layers in bulk heterojunctions
TL;DR: A key finding of this study is that, in contrast to a previous report, the annealing process does not converge at the short time scales reported and it is found that the self-assembly of the blends is characterized by three rate dependent stages that require much longer simulations to approach convergence.
Journal ArticleDOI
Effect of polymer-filler interaction strengths on the thermodynamic and dynamic properties of polymer nanocomposites
Monojoy Goswami,Bobby G. Sumpter +1 more
TL;DR: There are two kinds of "clustering transitions:" one due to thermodynamic and another due to the dynamical response of the system, and these are shown by examining the structure and dynamics of polymer nanocomposites using stochastic molecular dynamics simulations.
