|Title:||Can attenuated total internal reflection-fourier transform infrared be used to understand the interaction between polymers and water? A hyperspectral imaging study||Authors:||Mukherjee, Sindhuraj; Martínez-González, J.

The hydrophobicity of two categories of polymeric biomaterials is characterised using contact angle (CA) measurements and their relationship with the band area of the OH stretching v S vibration of water over time is presented. This is supported with correlations between CA data and single wavenum-ber intensity values (univariate analysis). Multivariate analysis of the spectra captured at the OH stretch for all polymers is carried out using principal component analysis to study the spatial variation in the interaction between the polymeric surfaces and water. Finally, a comparison between the univariate and multivariate strategies is presented to understand the interaction between polymeric biomaterials and water.||Funding Details:||European Commission - Seventh Framework Programme (FP7)||Type of material:||Journal Article||Publisher:||IM Publications Open||Journal:||Journal of Spectral Imaging||Volume:||6||Copyright (published version):||2017 the Authors||Keywords:||HDMSO; ATR-FT-IR; Polymer; Hydrophobicity; Silicon; Water; Hyperspectral imaging; Wetting||DOI:||10.1255/jsi.2017.a3||Language:||en||Status of Item:||Peer reviewed|
