Microphase separation in nonequilibrium biomembranes.
Compositional heterogeneities of cell membranes are thought to play an important role in many physiological processes. We study how variations in the membrane composition can be driven by nonthermal fluctuating forces and therefore show how these can occur relatively far from any critical point for the membrane. We show that the membrane steady state is not only controlled by the strength of th...
متن کاملFlexible Epoxy Resin Formed Upon Blending with a Triblock Copolymer through Reaction-Induced Microphase Separation
In this study, we used diglycidyl ether bisphenol A (DGEBA) as a matrix, the ABA block copolymer poly(ethylene oxide-b-propylene oxide-b-ethylene oxide) (Pluronic F127) as an additive, and diphenyl diaminosulfone (DDS) as a curing agent to prepare flexible epoxy resins through reaction-induced microphase separation (RIMPS). Fourier transform infrared spectroscopy confirmed the existence of hydr...
متن کاملMicrophase separation induced by interfacial segregation of isotropic, spherical nanoparticles.
In a recent experiment by Chung et al. [Nano Lett. 5, 1878 (2005)] and simulation by Stratford et al. [Science 309, 2198 (2005)] on immiscible blends containing nanoscale particles, it was shown that the phase separation of the two polymers can be prevented as a result of the aggregation of the nanoparticles at the interfaces between the two polymers. Motivated by these studies, we performed la...
متن کاملMicrophase separation in binary polymeric micelles
2014 A theoretical analysis of microphase separation in binary micelles is presented. We consider micelles consisting of two kinds of diblock copolymers such that the micellar corona contains two chemically distinct block types (A and B). Both intramicellar and intermicellar processes may occur. We focus on intermicellar segregation occurring after a quench yielding complete intramicellar micro...
متن کاملPhase and microphase separation in polymer blends
When two different polymers are mixed, they usually demix because of the slight repulsive interaction that exists between their monomers. This is general and may be related to phase separation in two component mixtures. When the same polymer blend is cross-linked in the one phase region, elastic forces develop and do not let this to occur. There results a microphase separation, with coexistence...
