Synthesis and Water Retention Properties of Poly(Acrylamide)-g-Kenaf Fiber Hydrogel
The purpose of this research was to study water retention properties of superabsorbent hydrogel based on poly (acrylamide)/biofiller hydrogel and urea liquid fertilizer, by solution polymerization. Kenaf fiber (KF) was used as biofiller and the preparation of the poly (acrylamide)-grafted-kenaf fiber (PAAm-g-KF) hydrogel was carried out by polymerizing the monomer. Urea fertilizer was employed as polymerization media. N,N’-methylene bisacrylamide (MBA) was used as a crosslinker and ammonium persulfate (APS) as an initiator. Water retention of the hydrogel was studies in soil with three different samples (Controlled, PAAm Hydrogel, PAAm-g-KF). The PAAm-g-KF was also applied to agricultural field. The results show that PAAm-g-KF greatly improved water retention in the soil and agricultural field.
