| Summary: | The effect of ultraviolet radiation on tensile properties, water absorption and optical properties of polypropylene (PP) reinforced with durian skin nanofibre (DSNF) composites was investigated. DSNF was obtained from fermentation of durian skin fibre using Rhizopus oryzae. X-ray diffraction (XRD) analysis and Sherrer equation were applied to measure the average particle size of DSNF which was determined as 51.2 nm. PP and DSNF were melt-blended in a Haake internal mixer before compression moulded into composite specimens. The composites were exposed under ultraviolet (UV) radiation to simulate the effect of sunlight. The significant effect of maleic anhydride polypropylene (MAPP) was observed by the improvement recorded in tensile properties and reduction of water absorption in PP/DSNF composite. The colour index of composites increased with UV radiation exposure. Transmission electron microscope (TEM) images showed DSNF was well-dispersed in PP matrix in the presence of MAPP.
Kesan ultraungu (UV) terhadap sifat tegangan, penyerapan air dan sifat optik
bagi polypropylene (PP) diperkuatkan dengan nanofiber kulit durian komposit telah
disiasat. DSNF telah diperolehi daripada process penapaian fiber kulit durian
menggunakan Rhizopus oryzae. Analisis difraksi sinar-x dan persamaan Sherrer telah
digunakan untuk mengukur purata saiz zarah untuk DSNFyang telah diperolehi sebanyak
51.2nm. PP dan DSNF telah dicampur dalam pembancuh Haake sebelum mampatan
dibentuk menjadi spesimen komposit. Komposit telah didedahkan di bawah radiasi
ultraungu (UV) untuk mensimulasikan kesan cahaya matahari. Kesan yang penting
terhadap polipropilena maleik (MAPP) telah diperhatikan dan setiap peningkatan dalam
sifat tegangan dan pengurangan penyerapan air dalam komposit PP / DSNF telah direkod.
Indeks warna komposit meningkat dengan pendedahan radiasi UV. Imej mikroskop
elektron penghantaran (TEM) menunjukkan DSNF telah disebarkan dengan baik dalam
matriks PP dengan kehadiran MAPP. |
