Micellization of block copolymers

Inkjet printing is familiar as a method of printing text and images onto porous surfaces. In the last few years it has been used as a free-form fabrication method for building three-dimensional parts and is being explored as a way of printing electrical and optical devices, especially where these involve organic components. Inkjet printers are also being used to produce arrays of proteins and nucleic acids. The need for a versatile inkjet technology for free-forming materials and for multilayer devices raises a number of materials problems that do not apply to conventional printing of images. Higher resolutions will be needed if organic transistors are to be printed. Also, it must be possible to print pinhole-free layers to avoid shorting of devices. Multiple layers must be printed such that they mix and react to form a single material or such that they form discrete unmixed layers. Printing on dense rather than porous substrates will be the norm. This article reviews the range of materials that has been ...

Pluronic® block copolymers as novel polymer therapeutics for drug and gene delivery

L'etude en fonction de la concentration du copolymere de la variation des proprietes spectroscopiques du pyrene provoquee par son partage entre les phases micellaires et aqueuses permet de determiner les concentrations critiques micellaires et les coefficients de partage

Poly(styrene-ethylene oxide) block copolymer micelle formation in water: a fluorescence probe study

Des copolymeres bi- et trisequences forment en solution aqueuse des micelles spheriques de 2 types dont les dimensions respectives sont constantes dans le domaine de concentration 2•10 −5 −2•10 −3 g/ml. La fraction en masse des particules les plus grosses decroit quand la concentration augmente. Les petites particules (20 nm de rayon hydrodynamique) sont des micelles regulieres avec un nombre d'association de quelques centaines; les grosses particules (65 nm) sont des amas constitues de dizaines de micelles

Fluorescence probe techniques used to study micelle formation in water-soluble block copolymers

An ink composition, preferably for ink jet printing, contains a liquid carrier, a colorant, and a polyalkyleneimine/alkylene oxide block copolymer, preferably polyethyleneimine/propylene oxide/ethylene oxide block copolymer, and/or a primary or secondary polyoxyalkylene amine.

Ink for ink jet printing

PS-PEO di- or triblock copolymer micelles of various compositions and molecular weights in waterwere investigated by light scattering. The hydrodynamic radius values for the micelles were in good accord with the scaling relationship of Halperin's star model. The star model was then incorporated into the data analysis to obtain the aggregation number and core radii. With these parameters the validity of the Noolandi-Hong mean density micelle model by using their equations to calculate the Flory-Huggins parameters for the interaction of PEO-water and PEO-PS.
