Nanoporous Linear Polyethylene from a Block Polymer Precursor.

The article discusses the development of nanoporous membranes generated from linear polyethylene (LPE)-polylactide (PLA) triblock copolymers. Researchers use polymerization mechanisms to prepare LPE block polymers containing a sacrificial block and employ a selective etching protocol to develop nanoporous LPE. By analyzing the PLA-LPE-PLA (LEL) triblocks, researchers observe that nanoporous membranes shows the chemical and thermal stability of LPE materials.
