Dissertation note: Project Paper (Bachelor of Applied Science (Honours) Material Technology) -- Universiti Malaysia Pahang – 2017 Abstract: Demand on nanotechnologies product initiate to many studies and investigations to produce better applications. In this research, the polyvinyl alcohol (PVA) and carboxymethyl cellulose (CMC) were synthesized successfully to fabricated a nanofiber by using electrospinning method. The ratio of CMC and PVA is 3:7 with the concentration of 1.5 wt% and 11 wt% respectively. It was then blended into different volume of AgNPs. The surface morphology of CMC/PVA incorporated with AgNPs at 6.67 v/v%, 13.33 v/v% and 20 v/v% were observed under field emission scanning electron microscope shown uniform and smooth nanofibers with average diameter of 126.90 ± 27.56, 126.90 ± 27.50, 141.26 ± 25.66 and 114.86 ± 23.79 nm respectively. Thermo gravimetric analysis discovered the higher weight loss of 88.12 % in fiber containing 6.67 v/v% of AgNPs. Meanwhile, FTIR result demonstrated that all nanofibers presented O-H group in range of 3300 - 3600 cm¯¹ and C-O stretching vibrations in range of 1055 - 1138 cm-1. All peaks showed the shiffness to the left as the amount of AgNPs were increased. Hence, the study on the properties of CMC/PVA incorporated with AgNPs nanofibers might be suitable as reference for various applications such as tissue engineering, drug delivery, water filter, sensors and energy storage.

Demand on nanotechnologies product initiate to many studies and investigations to produce better applications. In this research, the polyvinyl alcohol (PVA) and carboxymethyl cellulose (CMC) were synthesized successfully to fabricated a nanofiber by using electrospinning method. The ratio of CMC and PVA is 3:7 with the concentration of 1.5 wt% and 11 wt% respectively. It was then blended into different volume of AgNPs. The surface morphology of CMC/PVA incorporated with AgNPs at 6.67 v/v%, 13.33 v/v% and 20 v/v% were observed under field emission scanning electron microscope shown uniform and smooth nanofibers with average diameter of 126.90 ± 27.56, 126.90 ± 27.50, 141.26 ± 25.66 and 114.86 ± 23.79 nm respectively. Thermo gravimetric analysis discovered the higher weight loss of 88.12 % in fiber containing 6.67 v/v% of AgNPs. Meanwhile, FTIR result demonstrated that all nanofibers presented O-H group in range of 3300 - 3600 cm¯¹ and C-O stretching vibrations in range of 1055 - 1138 cm-1. All peaks showed the shiffness to the left as the amount of AgNPs were increased. Hence, the study on the properties of CMC/PVA incorporated with AgNPs nanofibers might be suitable as reference for various applications such as tissue engineering, drug delivery, water filter, sensors and energy storage.
