Abstract
he First Chapter: Introduction This chapter introduced a scientific literature survey on wound dressing
material and their types especially aerogel, the polymers that used for
aerogel preparation such as carrageenan and cellulose nanocrystal.
Additionally, the significant properties of wound dressing materials and
their biological application as well as the silver nanoparticles as
antimicrobial agent have been involved.
The Second Chapter: Experimental
This part describes the preparation of Carboxymethyl cellulose
nanocrystal (CM-CNC) with three different degree of substitutions via a
two-step reaction. First, CNC was treated with alkali (ex. NaOH) in the
presence of isopropanol. Such treatment facilitate the swelling and
penetration of alkali into the CNC structure. In the second step, CM-CNC
was formed by reacting three different concentrations of
monochloroacetic acid (0.9 ml,1.8 ml and 3.6 ml) and alkali-treated CNC
under heating.
It describes synthesis of silver nanoparticles (AgNPs) in its solid state via
reductant and stabilizing agent that mediated by using CM-CNC Sample
that prepared using 0.9 ml Chloroacetic acid as it was found to be
completely soluble in water so that selected for AgNPs preparation.
