Os efeitos da polpação kraft nas propriedades interfaciais da polpa de eucalipto brasileiro foram investigados usando titulação com polieletrólito (PT) e medidas de ângulo de contato. Mudanças na composição química da superfície foram avaliadas por espectrometria de reflexão total atenuada no infravermelho (FTIR-ATR), combinada com análise de componentes principais (PCA). O aumento do álcali at...
