1. 21. Novel Porous Films from Functional and Biocompatible Linear-Dendritic Hybrids

   Författare :Marie V. Walter; Michael Malkoch; Steve P. Rannard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poly ethylene glycol ; poly caprolactone ; linear-dendritic hybrid; click chemistry; CuAAC; thiol-ene chemistry; amphiphilic polymer; honeycomb film; isoporous film; thiol; dendrimer;

   Sammanfattning : In the last decades, the fabrication of ordered nano- and microporous structures has attracted increasing interest due to their specific properties and multiple possible applications in electronics, as templates or in the biological field. The development of such materials has been favored by the introduction of the simple breath-figure templating method in the 1990’s. LÄS MER
