Abstract

2013) Preparation and characterisation of plastic material for liver injury stress assessment model use, Materials Research Innovations, 17:sup1, 107-111 To link to this article: http://dx.A series of plastic materials for an organs injury stress assessment model use were prepared using a blend of potassium stearate (PS), sodium stearate (SS), polyvinyl alcohol (PVA) and paraffin liquid (PL) at various weight ratios. The mechanical properties of the materials were investigated via a compression test using Instron, and the results indicated that the PS/SS/PVA/PL blend with a weight ratio of 0?35 : 0?35 : 0?02 : 0?28 had superior plastic deformation properties. The PS/SS/PVA/PL blend's weight ratio of 0?35 : 0?35 : 0?02 : 0?28 was characterised by using Fourier transform infrared spectroscopy, a scanning electron microscope and differential scanning calorimetry. For a comparison, blend samples of PS/SS/PVA/PL with weight ratios of 0?68 : 0 : 0?2 : 0?30 and 0 : 0?68 : 0?2 : 0?30 were measured using the same methods. The resultsshow that the plastic deformation mechanism is due to the optimal combination of weight ratio of the PS and the SS, and that the carbon chain in the PVA is a backbone of the slip function.
