Mechanical properties of deep eutectic solvent assisted poly(polyol-co-citrate) polymers

These data were generated as part of a Swiss National Science Foundation funded visitor exchange program with the Optics Laboratory at EPFL on imaging through biofibers. One of the types of material studied was deep eutectic solvent assisted poly(polyol-co-citrate) polymers (DES citrate polymers). These are transparent, enabling possible application in optics, flexible, and have been shown to be biocompatible.

DES-poly(polyol-co-citrate) polymers require several days cross linking time (curing time), typically 10 days at 80oC to become gel like materials. The aim here is to understand their mechnical properties as a function of curing time to obtain materials optimally matched to the mechanical properties of biological tissue with a view towards implants. The AFM files published here contain data on Young's modulus, adhesion, and dissipation for samples cured for different numbers of days, as well as the corresponding topography images.

Associated FTIR spectra for the DES poly(1,8-octanediol-co-citrate) samples are included.

The AFM data were recorded using Peak Force QNM on a Bruker FastScan AFM in the EPFL Center of MicroNanoTechnology
