520 $a CHAPTER ONE introduces the PHBV polymer, natural cellulose fibers, and polymeric composites including the fiber/matrix interface. The degradability of PHBV is also briefly discussed.
520 $a Recently, there has been considerable research on biodegradable polymers because of the complex plastic waste management created by the mostly non-degradable polymers and polymer-based composites. In this dissertation, physical and mechanical properties of poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV), a degradable polymer, and its pineapple fiber-reinforced composites are discussed.
520 $a CHAPTER TWO describes the effects of thermal processing time on the properties of PHBV. At processing conditions of 180°C and 140 MPa, PHBV underwent significant, random chain scission. As a result, tensile properties deteriorated. DSC and SAXS results show that thermally degraded PHBVs had different thermal properties and lamellar morphology.
520 $a CHAPTER THREE reports the effects of <super>60</super>Co γ-radiation on the properties of PHBV. Under <super>60</super>Co γ-radiation random chain scission but no cross-linking occurred in PHBV. Chain scission occurs probably in the amorphous region. As a result, thermal and tensile properties are significantly affected.
520 $a CHAPTER FOUR describes properties of pineapple fibers, the interface between pineapple fiber and PHBV, and properties of pineapple fiber-reinforced PHBV “green” composites. Pineapple fiber has enough strength to be used as reinforcement in composites with intermediate strength. Interfacial shear strength was moderate. The mechanical properties of PHBV were significantly improved, and were comparable to some woods.
520 $a CHAPTER FIVE presents the mechanical and thermal properties of unidirectional, degradable, environment-friendly “green” composites made from pineapple fibers and PHBV resin. Tensile and flexural properties of the “green” composites with different fiber contents were investigated. The presence of pineapple fibers did not affect the non-isothermal crystallization kinetics, crystallinity, and thermal decomposition, but significantly improved the mechanical properties, including tensile and flexural properties, of PHBV resin.
520 $a CHAPTER SIX discusses degradation of PHBV in a compost medium. It is suggested that enzymatic degradation of PHBV in the compost medium occurs from the surface and that the degraded material leaches out. Importantly, the enzyme seems to remove polymer chains in both crystalline and amorphous regions indiscriminately.
