Mechanochemical Fabrication of Multicomponent Copolymer Biomaterial

Polylactide (PLA) (Natureworks 4043D, Minnetonka, MN, USA) with molecular weight (Mw) of 100 kDa; polycaprolactone (PCL) with Mw of 67 kDa and gelatin (Chimmed, Moscow, Russia) were used as received. Chitosan with Mw of 80 kDa and degree of deacetylation of 0.89 as well as oligo(l-lactide) with Mw of 5 kDa from l-lactic acids (Panreac, Barcelona, Spain) were synthesized in Enikolopov Institute of Synthetic Polymeric Materials. Multicomponent copolymer-contained system based on polycaprolactone/poly(l-lactide)/oligo(l-lactide)/chitosan/gelatin (PPCOG) was obtained via mechanochemical approach and characterized as reported earlier [29 (link)]. Hexafluoroisopropanol (HFIP) was purchased from “Chemmed” (Moscow, Russia) and used as received.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
