Graphene nanoplatelets are chemically crosslinked to aramid nanofibers through a phosphorus trimer to fabricate ultratough, thermoconductive, flame retardant, and EMI shielding films.

We present a brief account of the theory of diffusion-influenced kinetics of reactions involving polymers. The review will be based on the recent contributions from the authors. Both intrapolymer and interpolymer reactions are considered, and the effects of various physical factors, such as the chain length, chain stiffness, and hydrodynamic interactions, are described within a unified theoretical framework. Key Words: Diffusion-influenced kinetics, Intrachain and interchain reactions

Conformational transitions of polymers interacting with membranes are studied theoretically for various adsorbed states. The nature of transitions is determined by the conformational fluctuations of polymers and membranes, which are controlled by their stiffness. The condition and nature of polymer integration in an alpha-helix aggregate within a hydrophobic membrane is also discussed.
The polymer translocation across membranes is studied as a stochastic process over a free energy barrier, where the mean first passage time is examined analytically as a measure of translocation rate. The nonequilibrium fluctuations of... more
The polymer translocation across membranes is studied as a stochastic process over a free energy barrier, where the mean first passage time is examined analytically as a measure of translocation rate. The nonequilibrium fluctuations of chemical potential difference enhance directed transport of polymers, giving rise to a resonant activation. The translocation time of a long-chain polymer is found to be very sensitive not only to the average value of chemical potential difference but also to its fluctuation.
