AVALIAÇÃO DE SISTEMAS DE PBH POR RELAXOMETRIA DE CICLO RÁPIDO DE CAMPO

open access: yesSemioses Inovação Desenvolvimento E Sustentabilidade, 2018
Sistemas de poli (3-hidroxi butirato) (PHB) foram analisados por relaxometria de ciclo rápido de campo (Fast-field cycling-FFC), visando entender a homogeneidade dos sistemas em face das interações criadas nestes e consequentemente da dispersão de fases e nanopartículas, propiciando ou não sistemas heterogêneos, porém homogeneamente dispersos.
