Embodiment Construction

[0032] By using membranes obtained from the preparation method according to the invention, the prior art pressure drop problem along the module is eliminated and droplet formation does not require cross-flow, which in turn allows a wider range of design options. New products applied to various fields can be commercially viable by solving the problems of existing technical solutions regarding cost, scale-up and durability.

[0033] Due to the development of highly monodisperse membrane emulsification technology, the preparation of microcapsules and microspheres is an emerging technology that has been decisively impacted. An example of an application stemming from the use of membrane technology where particles require sizes and monodisperse that are difficult to achieve by other conventional techniques is (i) encapsulation of anticancer drugs in drug delivery systems that, after injection into the blood, slow release into target organs, (ii) preparation of porous beads used as f...

Abstract

The present invention provides a manufacturing method of a membrane, a membrane obtained therefrom, and a use of said membrane for membrane emulsification. A desired shape of the membrane pores for spontaneous interfacial tension driven droplet formation is achieved by stretching the membrane material containing pores with a first shape, such that a second shape, i.e. the pores having an aspect ratio greater or equal to 3, is obtained.

Description

technical field [0001] The present invention generally relates to the field of membrane emulsification. More particularly, the present invention relates to a method of producing a membrane for membrane emulsification, a membrane obtained by the method, and an emulsion obtained by using the membrane. Background technique [0002] Emulsions are important commodities in the food, cosmetic and pharmaceutical industries. Emulsions consist of two or more immiscible phases such as oil and water or water and air, where the dispersed phase is suspended in the form of small liquid droplets in the continuous phase. Many of the most notable properties of emulsion-based products such as shelf life, appearance, structure, odor, degree of encapsulation and release rate are determined by the size of the liquid droplets they contain. The size and size distribution of the droplets is critical to the stability of an emulsion as it determines the rate of coalescence and the suitability of the...
