Abstract

To contribute to the development of new alternatives in the area of polymers for biomedical applications, the surface modification of a cotton gauze grafted with a N-vinylcaprolactam (NVCL) by ionizing gamma radiation was developed, in to provide it with more physical and chemical properties. To verify that the grafting was successful, the samples were analyzed and characterized by attenuated total reflectance, by Fourier transform infrared spectroscopy, differential scanning calorimetry, and thermogravimetric analysis. The grafted samples showed greater hydrophilicity and affinity with drugs, as well as a critical solution temperature between 33 and 40 °C; therefore, this material was implemented as administrator of AgNPs in controlled doses, thus obtaining a material with greater absorption, anti-inflammatory and with antimicrobial characteristics.
