Environmentally Friendly Novel Maleated Poly(vinyl alcohol) Grafted 1, 4-Butanediol Modified with Biopolymer for Encapsulation of Capsaicin

Nowadays, hydrogels are widely used in many fields, for instance as biosensors, in tissue engineering and in agriculture due to their high swelling behavior in water and their softness. The objective of this work was to study the preparation and physical properties of maleated poly (vinyl alcohol) (...

Summary:Nowadays, hydrogels are widely used in many fields, for instance as biosensors, in tissue engineering and in agriculture due to their high swelling behavior in water and their softness. The objective of this work was to study the preparation and physical properties of maleated poly (vinyl alcohol) (PVAM)- graft- butanediol (BDO) (PVAM- graft -BDO) using K 2 S 2 O 8 as an initiator. The highest grafting efficiency of 92% was found at 7:3 PVAM- graft -BDO. The swelling behavior of the PVAM- graft -BDO increased with an increasing BDO content. The highest swelling ratio of the PVAM- graft -BDO of 250% was found at 7:3 PVAM:BDO. Moreover, the maximum tensile strength of the PVAM- graft -BDO was observed at 9:1 PVAM:BDO. The elongation at break of the PVAM- graft -BDO was improved by the addition of natural rubber- graft- cassava starch (NS). The PVAM- graft -BDO was used as a polymer matrix for the encapsulation of capsaicin. The results showed that the rate of capsaicin release from the polymer matrix in a water medium was controlled by the BDO portion and the NS content. After use, it was easily degraded in natural soil.
