Development Studies of Biodegradable Pressure Sensitive Adhesives and Fiber Reinforced Polyester Composites from Castor Oil | Chapter 09 | Theory and Applications of Chemistry Vol. 3
The potential use of castor oil in
preparation of novel biodegradable polymeric pressure sensitive adhesives and
fiber reinforced polyester composites was investigated. A biodegradable
oligomeric fumarated resin was prepared by the insitu hydroxylation of castor
oil followed by maleation under controlled reaction conditions. Then two
varieties of biodegradable pressure sensitive adhesives (PSAs) were prepared by
further reacting the resin with co-monomers vinyl acetate and methyl acrylate.
The PSAs were characterized for biological and physicochemical properties;
namely thermal stability, transparency, chemical resistance, biodegradability,
and tensile strength. Fiber reinforced polyester composites were prepared by
free radical polymerization of oligomeric fumarated resin mixed with different
propositions of Jute and Sisal fiber. The composites were then analyzed for
physicochemical by AT-IR, SEM, TGA and DSC techniques, The results indicate
that castor oil-based PSA films and tapes have applications in various fields
including flexible electronics and medical devices because of their thermal
stability, transparency, chemical resistance, and potential biodegradability
from triglycerides. Mechanical characterization of the composites was also done
and the results positively indicated the Sisal and Jute fibers have the
potential to be used as substitutes for synthetic fibers in green composites.
The composites can be used for the fabrication of eco-friendly materials.
