The samples were prepared in film shape by solution method, in which, the content of PEO was changed from 1 wt.% to 5 wt.% and the content of allopurinol was fixed at 10 wt.% in comparison with carrageenan weight. FTIR , FESEM, UV-Vis methods were used to evaluate characterizations and morphology of CG/PEO/allopurinol films.</p>}, number={2}, journal={Vietnam Journal of Science and Technology}, author={Phuong, Nguyen Thi and Chinh, Nguyen Thuy and Manh, Vu Quoc and Hoang, Thai and Trung, Vu Quoc}, year={2020}, month={Mar.}, pages={219–227} }
