TP 6: Simultaneous Polymerization of Two or More Twin Monomers for Synthesis of Functionalized Pebble Gel Hybrid Materials (1. FP)
Project Manager: Prof. Dr. Stefan SpangeTU Chemnitz, Chair of Polymer Chemistry, Chemnitz
Project Goals:
- Synthesis and charakterization of new materials:
Simultaneous twin polymerizaion as new concept for the synthesis of nanostructured hybrid materials
Porous, organic functionalized nondeformable silica hybrid materials
Synthesis of partly soluble nanostructured hybrid materials through twin polymerization
Fabrication of polymers with soluble content by selective modification of the monomer structureSo far mainly insoluble materials with cross-linked structure
Results:
The development of the simultaneous twin-polymerization (STP) was the dominating and most important result of the first funding period.
STP has been proven to be a fundament with great synthetic potential for other working groups and partners within the industrial sector.
The following scheme illustrates the principle of STP for production of the ternary hybrid material
SiOX/(Si(R2)2-O-)y/phenolic resin as an example.
| Figure 1: | Simplified description of the STP as shown for a specific ternary Silica-Siloxane/phenolic resin nanostructured hybrid material. Si as central atom can be replaced by other elements such as boron, titanium or tin. . |
The idea of STP has inspired a lot of further synthetic procedures to synthesize any kind of hybrid material on demand.
It is possible to fabricate novel materials by STP which have not yet been available by conventional synthetic methods.
