摘要: Abstract Chitosan nanoscaffold obtained directly from chitin whiskers is proposed. The structural analysis by nuclear magnetic resonance ( 1 H NMR) confirms that the alkaline treatment changes whisker to chitosan with as high 98% degree of deacetylation. micrographs scanning electron microscope (SEM) and transmission (TEM) confirm short fiber develop itself be a network in nano-scale or nanoscaffold. increase viscosity compared suggests scaffold performs polymer bulk solution. increases surface area, pore volume, size studied Brunauer–Emmett–Teller (BET) gas adsorption inform development porous structure chitosan. well dispersion solution easily controlled solvent polarity salt concentration.
