Water Vapor Permeability (WVP)
WVP = [ Flux / A. P0 (RH1RH2) ] * xwhere:
x : film thickness (m); A : film surface area exposed to permeant (m2)
P0 : vapor pressure of pure water (1753.55 Pa at 25 oC)
(RH1RH2) : relative humidity gradient used in experiment
X-Ray Diffraction (XRD)Ctl = [ (II) / I ] x 100%
where:
I : diffraction intensity assigned to (200)
plane of cellulose
I : intensity measured at 2 18* calculated in x-ray diffraction angle width of
5o to 30o (2) with power of 20 kV and 2mA
THE FORMULAS :
Derivative Thermo-Gravimetric (DTG)
thermal stability of few amount (mg)
of sample placed on aluminum glass
was tested in nitrogen condition &
heating rate of 10 oC per minute.

For OBJECTIVE 2 2. To measure critical factor ranking of nanocomposite film product properties
-
1. Succeeded to represent whole
processes of the nanocomposite
production, as solution for the
complexity & inter-
dependencies2. Potentially contributes to cost &
time efficiency
ADVANTAGE & DISADVANTAGEOf This Model
1. Does not yet
represent a
physical model
(user interface)2. Needs current
data update of 3 product properties
(XRD, DTG & WVP)
-
CONCLUSION1. BPMN model designed
& simulated the
production system of
sorghum-based
nanocomposite film
2. BPMN analyzed influences
of varied hydrolysis time
& plasticizer ratio on 3 product properties (XRD,
DTG, WVP)
RECOMMENDING REMARKSIt is required to add more updated data of XRD, DTG & WVP product
properties for more advanced model
validation, & represent the system in
physical model (ex: user interface)
