Modification of LDPE molecular structure by gamma irradiation for bioapplications
LM Ferreira, AN Falcão, MH Gil - … and Methods in Physics Research Section …, 2005 - Elsevier
The surface properties of low-density polyethylene (LDPE) can be modified by the grafting of
2-hydroxyethyl methacrylate (HEMA). This was done aiming at the production of new
materials suitable for bioapplications. Samples with different monomer concentrations were
prepared from LDPE particles by gamma irradiation, following different irradiation protocols,
including irradiation in presence and absence of air. The samples were characterized by
thermal analysis techniques (DSC and TGA) and by Fourier transform infrared spectroscopy …
