Abstract
Evaluation of biobased content of biobased polymers and their composites by measuring carbon-14 using accelerator mass spectrometry (AMS) was described. Biobased carbon content can be evaluated by measuring carbon-14 content using AMS, since biomass includes carbon-14 atoms in atoms of its constitution and fossil include no carbon-14 atoms in it. Sample preparation and pretreatment for AMS were explained in detail. Results of biobased content of plants, polymers and polymer composites by AMS were shown. Reproducibility and accuracy of AMS measurement were investigated. Evaluation method for biobased polymer content of polymer products can be also obtained using results by AMS. Examples of these evaluation results were shown. The international standards concerning this method were also described.
