Summary: This study investigates the influence of initiator type on the morphology of PP/PS composite particles. It was found that cationic initiator VA-044 led to the formation of multilayer structures in the composite particles, while the nonionic initiator VA-086 resulted in void structures with a PP shell encapsulating the PS phase. Anionic initiator V-501 led to PS primarily attaching to the outer surfaces of PP particles. These differences were due to electrostatic interaction between the initiator and PP particles of negative zeta potential.

Summary: Interest in transparent conductive materials, particularly graphene and its derivatives, has grown in recent years due to their unique optical and electrical properties. While previous studies have explored replacing indium doped tin oxide with graphene derivatives, a simple and effective method for producing competitive transparent conductive films (TCFs) using graphene has not yet been established. This article introduces a new procedure for fabricating TCFs with high quality, uniformity, and stability, utilizing a combination of drop casting, reduction with triethylenetetramine vapors, and doping with nitric acid. The resulting TCFs exhibit comparable conductivity to existing literature, but with the advantages of simplicity, low cost, scalability, and stability.

Summary: This study investigates the shock behavior of three different polymers through molecular dynamics simulations. The results reveal specificities in the shock behavior of polymers, including deviations from the linear relation between shock velocity and particle velocity, as well as differences in shear stress relaxation behind the shock front. It is found that the deviation of the Hugoniot locus is related to the change in the relative contribution of bonding and non-bonding potential energies, while polymers with higher glass transition temperatures exhibit slower shear stress relaxation.

Summary: The difference in leaching of amylopectin from cellulose/amylopectin/1-butyl-3-methylimidazolium chloride ([Bmim][Cl]) blends during regeneration in water and aqueous ethanol has been studied. Molecular dynamics simulations showed that the dissolution and regeneration mechanisms of amylopectin in [Bmim][Cl] are similar to cellulose in ionic liquids. Water regeneration leads to weak electrostatic interactions, resulting in high leaching of amylopectin. In contrast, ethanol-water interactions enhance electrostatic interactions among amylopectin chains, limiting amylopectin leaching in aqueous ethanol.

Summary: Multi-physical fields solution processing strategy is a universal and facile method for preparing various conjugated polymer films and high-performance devices. In this study, we employed a combined microfluidic flow and ultrasonication strategy (FU) for processing CP solutions, and found a pronounced synergetic effect in promoting the pre-ordering of chains in solution. The conformation order and anisotropy of the solution were revealed through various characterizations. A non-classical nucleation model for polymer crystallization in non-equilibrium solution processing was confirmed. The roles of microfluidic flow and ultrasonication in chain aggregation and crystallization were addressed through multi-physical simulations. Compared to pristine solutions, the FU strategy showed improved solution anisotropy and crystallization kinetics, resulting in higher crystallinity in films and increased mobilities in OFET devices. The FU processing strategy provides a universal approach for regulating chain conformation and aggregation in conjugated polymer solutions.
