Abstract
This study involves the efficient fabrication of a novel radiation phantom material made of natural wood Rhizophora spp. (R. spp.) particleboard, using soy protein concentrate (SPC), NaOH, and a bio-based curing agent (itaconic acid polyamidoamine-epichlorohydrin) (IA-PAE) as critical components. The structural properties of the phantom samples were investigated by field emission scanning electron microscopy (FE-SEM). Mass attenuation coefficients were determined using photons at XRF energies between 16.59 and 25.26 keV. CT numbers, electron densities, and density profiles were estimated using an X-ray computed tomography (CT) scanner and compared to water. The results showed that the physical, mechanical, and dimensional stability properties of the particleboards were significantly enhanced with 15 wt% IA-PAE content. All cured particleboard samples showed values of mass attenuation coefficients and an effective atomic number close to that of water with p-value>0.05. It was found that the CT number, electron density, and density profile of the particleboard phantom with 15 wt% IA-PAE agreed excellently with water at 80, 120, and 135 kVp CT energies. These findings indicate that NaOH/IA-PAE resin has the potency of ameliorating the performance capability of SPC-based adhesive, thereby making the R. spp. particleboard suitable as a tissue- and water-equivalent phantom material.
