Figure 3From: Polylactic acid composites incorporating casein functionalized cellulose nanowhiskersChange in relative reflectivity value when 0.01, 0.025, 0.05, 0.075, 0.1, 0.2, 0.25, 0.5 mM PLA solutions were flowed across the casein coated surface in sequence. Data is presented as mean standard deviation of five determinations and fit to the Langmuir isotherm (solid line).Back to article page
