Abstract:

The article are outlined the medicinal use of polymer materials and characteristics and described its preparation method and application for controlled drug release from polymer, polymer drugs, pharmaceutical formulations and packaging polymer materials three aspects. Meanwhile elaborates a novel well dispersed MWCNTs PMAA/MWCNTs nanohybrid hydrogels. The introduction of MWCNTs significantly improved pH-responsive hydrogels and mechanical strength, and which depending on the composition ratio of MWCNTs, particle size and concentration of crosslinker. Study found that hybrid hydrogel swelling rate significantly faster than the pure PMAA hydrogel swelling behavior and this is explained. Compressive stress - strain was found, MWCNTs load transfer heterozygous for improving mechanical properties of the hydrogel network compression plays an important role. MTT cell compatibility evaluation proves that this astute hydrogel biomedical research in particular has potential application value.
