Benefits of technology

This patent describes a method for making a porous microstructure. The method involves using a triplex process, which involves creating a polymer structure, then chemically removing certain parts of the structure to create a void. The resulting microstructure has a unique structure and can be used for various applications such as drug delivery or tissue engineering. The patent also includes a diagram showing the process and an electron microscopic image of the final porous microstructure. The technical effect of this patent is to provide a reliable method for producing porous microstructures with precise control over their structure and properties.

Problems solved by technology

However, the high porosity of the porous microstructure may bring about the disadvantage of a decreased mechanical strength.

Abstract

The invention relates to production of a porous microstructure using the high internal phase emulsion (HIPE) templating technology. The invented method involves subjecting an emulsion prepared by emulsification of two immiscible phases to forced sedimentation, such as subjecting the emulsion to centrifugation, so as to increase the volume ratio of the dispersed phase to the continuous phase to obtain a high internal phase emulsion (HIPE), following by curing the continuous phase, whereby the porous microstructure thus produced has an increased porosity.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority to R.O.C. Patent Application No. 109124248 filed Jul. 17, 2020 and R.O.C. Patent Application No. 110100498 filed Jan. 6, 2021, both of which are hereby incorporated by reference in their entirety.FIELD OF THE INVENTION[0002]The invention relates to a method for producing a porous microstructure, and generally relates to use of the high internal phase emulsion (HIPE) templating technology to prepare a porous microstructure.BACKGROUND OF THE INVENTION[0003]High internal phase emulsion templating is an emerging technology for producing porous polymeric material. The so-called “high internal phase emulsion” refers to an emulsion where an internal phase (namely, a dispersed phase) of emulsified droplets with a volume fraction of over 74.05% are dispersed in an external phase. That is to say, the total volume fraction of the internal phase exceeds the maximum space that monodispersed microspheres can occupy in th...
