“…Although FeCl 3 was can be used in fabrication of biocompatible materials ( Petrenko et al, 2011 ; Hege and Schiller, 2014 ), the cytotoxicity of the produced material still needs to be assessed. The result shows that the amount of FeCl 3 needs to be controlled properly as a high FeCl 3 load ([M]:[C] ratio of 400:1) condition is harmful to cells, but if controlled at a proper level (i.e., at [M]:[C] ratio of 800:1) the produced PCL is non-toxic to the cell and can be potentially used as cyto-compatible materials.…”

“…To decrease the toxicity and improve the energy efficiency towards the principle of green chemistry, various catalyst systems, and processing techniques were studied. Among different catalysts that have been investigated, iron (III) halides were found to be an effective catalyst and can be used in fabricating biocompatible materials ( Petrenko et al, 2011 ; Hege and Schiller, 2014 ). These studies have paved the way for intensifying the process.…”

We report on the ring-opening polymerization of ɛ-caprolactone incorporated with a magnetic susceptible catalyst, FeCl3, via the use of microwave magnetic heating (HH) which primarily heats the bulk with a magnetic field (H-field) from an electromagnetic field (EMF). Such a process was compared to more commonly used heating methods, such as conventional heating (CH), i.e., oil bath, and microwave electric heating (EH), which is also referred to as microwave heating that primarily heats the bulk with an electric field (E-field). We identified that the catalyst is susceptible to both the E-field and H-field heating, and promoted the heating of the bulk. Which, we noticed such promotion was a lot more significant in the HH heating experiment. Further investigating the impact of such observed effects in the ROP of ɛ-caprolactone, we found that the HH experiments showed a more significant improvement in both the product Mwt and yield as the input power increased. However, when the catalyst concentration was reduced from 400:1 to 1600:1 (Monomer:Catalyst molar ratio), the observed differentiation in the Mwt and yield between the EH and the HH heating methods diminished, which we hypothesized to be due to the limited species available that were susceptible to microwave magnetic heating. But comparable product results between the HH and EH heating methods suggest that the HH heating method along with a magnetic susceptible catalyst could be an alternative solution to overcome the penetration depth problem associated with the EH heating methods. The cytotoxicity of the produced polymer was investigated to identify its potential application as biomaterials.
