Reactive blending of Poly(lactic acid) and Thermoplastic starch
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 12/6/2020)The polymer blend between Poly(lactic acid) (PLA) and Thermoplastic starch (TPS) is problematic due to their incompatibility resulted from the difference between polarity and viscosity. Therefore, in the work, the viscosity ... -
Reactive Blending of Polyhydroxybutyrate and Poly (lactic acid)
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 12/6/2020)Polyhydroxybutyrate (PHB) and polylactic acid (PLA) are immiscible blends. Their blends have poor properties. This work aims to study compatibilization of polymer blend between PHB and PLA 2 methods; first the addition of ... -
Study and comparison mechanical properties of different Poly(lactic acid) grades with filler and plasticizers
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 17/8/2018)The aim of this research was to study and compare the effect of plasticizer type and content including the addition of talcum on mechanical and dynamic mechanical properties of poly(lactic acid). Two types of plasticizer ... -

Synthesis of Copolycarbonate from CO2 and Probability to Improve Impact properties of Poly (lactic acid)
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 17/8/2018)This work aimed to study the preparation of copolycarbonate based on carbon dioxide (CO2) and 1, 2-butylene oxide using zinc glutarate (ZnGA) as a catalyst. The effect of reaction time, temperature, and pressure on the ... -
Thermal and mechanical properties of poly(lactic acid)/pineapple leaf fiber biocomposite
Collection: Theses (Master's degree) - Polymer Science and Engineering / วิทยานิพนธ์ - วิทยาการและวิศวกรรมพอลิเมอร์Type: Thesis(Silpakorn University, 12/7/2019)Poly(lactic acid) (PLA) is one of bioplastics having great potential in production and application in industry. However, the using of PLA is still limited due to its poor resistance to high temperatures. Therefore, in ...
