Fabrication and characterization of biorenewable plasma polymer films using sandalwood oil precursor

摘要

Sandalwood oil is a natural, biorenewable oil which has many beneficial properties such as being anticarcinogenic and cytotoxic to some viruses, while being safe for human consumption. Therefore, thin films derived from sandalwood oil are of interest in the biomedical field. Here, thin films using sandalwood oil as the precursor are deposited via plasma polymerization with the aim of minimizing degradation of the precursor structure. The chemical properties of the plasma phase were measured by optical emission spectroscopy and the degradation pathways of the precursor molecules were elucidated via mass spectrometry. Combined with surface analysis of the thin films, partial structural retention of precursor molecules is demonstrated.
