In printed electronics, uniform and solute film formation by the inkjet method is very important. This study aims to clarify relationship between Marangoni convection generated adding surfactant thinning of film. First, four types surfactants were added one anisole-polystyrene solution with varying concentrations, then a little amount fluorescent polymer was as tracer each solution. Next, dropp...

A new and general approach is proposed to analyze the dynamics of a colloidal particle interacting with a nearby wall. This analysis can be used to determine the acting forces even when the system is non-stationary. As an illustration, we use total internal reflection microscopy to investigate the forces acting on a polystyrene sulfate latex particle as it is receding from a charged glass surface.

We introduce a novel and versatile approach for preparing self-assembled nanoporous multilayered films with tunable optical properties. Protonated polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) and anionic polystyrene-block-poly(acrylic acid) (PS-b-PAA) block copolymer micelles (BCM) were used as building blocks for the layer-by-layer assembly of BCM multilayer films. BCM film growth is go...

Capacitive Pressure Sensors In article number 2205324, Guorong Shan, Miao Du, and co-workers develop a method of liquid-liquid interface contact (MLLC) to pretreat the pristine poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) solutions. By dripping this resultant ink, ring-like film with interconnected networks that prefers high conductivity can be prepared due coffee ring eff...

An organic-organic blend thin film has been synthesized through the solution deposition of a triblock copolymer (Pluronic P123, EO20-PO70-EO20) and polystyrene (PS), which is called P123-PS for the blend film whose precursor solution was obtained with organic additives. In addition to having excellent insulating properties, these materials have satisfied other stringent requirements for an opti...

Inorganic barriers grown by atomic layer deposition (ALD) can overcome the stability issues originating from permeation of foreign species (water and oxygen) into polymer thin films. Alternatively, infiltration ALD bulk be used to modify its characteristic properties. In this study, feasibility growing an inorganic barrier with on polystyrene, poly(methyl methacrylate), poly(ethylene terephthal...
