Petersburg scientists have created a technology for a polymer like a «Swiss cheese»
Russian scientists have proposed a new method for producing polymers with preset properties. They took cheap raw materials — calcium carbide — and used the technology of vinylation, that is, they introduced CH = CH2 groups into it.
As a result, the scientists got ethers, which they could use to produce a polymer with a structure similar to Swiss cheese, with microscopic «holes». Microscopic «nanoholes» are evenly distributed throughout the polymer, and in its depth there are hollow spheres with very thin partitions, between which there are no connecting channels.
According to Valentin Ananikov, the head of the cluster catalysis laboratory at St. Petersburg State University and Corresponding Member of the Russian Academy of Sciences, it is possible to put some substance into the pores of the new material, for example, a medicine that will be preserved in them and will leave the polymer only under certain conditions.
The results of the study have been published in the journal ChemSusChem.
