| 要約: | This thesis aims to evaluate the characterization of graphite polyurethane composite
from renewable based oils. Virgin cooking oil (VCO) as a renewable resource is the
main substance in fabricating the renewable polyurethane (PU) and its graphite as
called polyurethane graphite (PG). The fabricating sample have two methods that is
open casting and heat press method. PU and PG with different percentage of graphite
as filler were investigated for structural, morphological, physical and mechanical
properties that going through a several testing including Optical Microscope (OM),
Scanning Electron Microscope (SEM), Ultraviolet-visible (UV-Vis), Fourier
Transform Infrared (FT-IR), Density Test, Tensile test and cross-link density. The
renewable polyurethane is namely as PU and polyurethane graphite is namely as
PG2, PG4, PG6, PG8, PG10 with subscript numbers indicate the weight loading of
graphite content was varied in the renewable polyurethane from 2, 4, 6, 8, and
10wt%. The result of SEM and OM showed that the graphite particles are randomly
distributed and homogeneously scattered well in the PU due to interconnected
interface within the matrix of polymeric composites. UV- Vis technique is used to
characterize the absorption, transmission and reflectivity of the PU and PG’s
otherwise the FT-IR is used for determine the composition and characterize the
polymer structure of PU and PG’s. As expected, the mechanical properties of
composites proven that the addition of graphite can change the matrix properties of
PU to improve modulus and consequent lowered the tan delta with respected of
increasing the temperature. The calculated cross-linked density of PU and PG
composites revealed the increment of graphite particle loading gives highest result of
cross-linking and this is due to the PG10 is the highest graphite content and the
highest value of storage modulus, highest value of tensile strength and the highest
value of young modulus. Therefore, the result shows the renewable polymer graphite
composite is suitable to be used in various composites applications. |
