In situ synthesis of bacterial cellulose/polycaprolactone blends for hot pressi...
Figueiredo, Ana R. P.; Silvestre, Armando J. D.; Neto, Carlos Pascoal; Freire, Carmen S. R.A series of bacterial cellulose (BC)/polycaprolactone (PCL) nanocomposite films were successfully prepared by supplementation of the BC culture medium with variable amounts of PCL powder followed by hot-pressing of the BC/PCL mixtures obtained after incubation. PCL powder was fully incorporated into the BC network during its production and did not change the BC network morphology. The obtained films showed a ho...

Figueiredo, Ana R. P.; Figueiredo, Andrea G. P. R.; Silva, Nuno H. C. S.; Barros-Timmons, Ana; Almeida, Adelaide; Silvestre, Armando J. D.tAntimicrobial bacterial cellulose/poly(2-aminoethyl methacrylate) (BC/PAEM) nanocomposites wereprepared by in situ radical polymerization of 2-aminoethyl methacrylate, using variable amounts of N,N-methylenebis(acrylamide) (MBA) as cross-linker. The obtained nanocomposites were characterized interms of their structure, morphology, thermal stability, mechanical properties and antibacterial activ-ity. The ensuin...

Figueiredo, Andrea G. P. R.; Figueiredo, Ana R. P.; Alonso-Varona, Ana; Fernandes, Susana C. M.; Palomares, Teodoro; Rubio-Azpeitia, EvaA series of bacterial cellulose-poly(2-hydroxyethyl methacrylate) nanocomposite films was prepared by in situ radical polymerization of 2-hydroxyethyl methacrylate (HEMA), using variable amounts of poly(ethylene glycol) diacrylate (PEGDA) as crosslinker. Thin films were obtained, and their physical, chemical, thermal, and mechanical properties were evaluated. The films showed improved translucency compared to B...
