Characterization of Rhizophora SPP. particleboards with SOY protein isolate modified with NaOH/IA-PAE adhesive for use as phantom material at photon energies of 16.59–25.26?keV

摘要

In this work,Rhizophora spp.particleboard phantoms were made using SPI-based adhesives, modified with sodium hydroxide and itaconic acid polyamidoamine-epichlorohydrin (0, 5, 10, and 15?wt%). An X-ray computed tomography (CT) imaging system was used to ascertain the CT numbers and density distribution profiles of the particleboards. The SPI-based/NaOH/IA-PAE/Rhizophora spp.particleboard phantoms with 15?wt% IA-PAE addition level had the highest solid content, flexural strength, flexural modulus, and internal bonding strength of 36.06?±?1.08%, 18.61?±?0.38 Nmm?2, 7605.76?±?0.89 Nmm?2, and 0.463?±?0.053 Nmm?2, respectively. The moisture content, mass density, water absorption, and dimensional stability were 6.93?±?0.27%, 0.962?±?0.037 gcm?3, 22.36?±?2.47%, and 10.90?±?0.86%, respectively. The results revealed that the mass attenuation coefficients and effective atomic number values within the 16.59–25.26?keV photon energy region, were close to the calculated XCOM values in water, with a p-value of 0.077. Moreover, the CT images showed that the dissimilarities in the discrepancy of the profile density decreased as the IA-PAE concentrations increased. Therefore, these results support the appropriateness of the SPI-based/NaOH/IA-PAE/Rhizophora spp.particleboard with 15?wt% IA-PAE adhesive as a suitable tissue-equivalent phantom material for medical health applications.
