Resumen
THE ACCUMULATION OF PLASTIC WASTE AND INFECTIOUS DISEASES HAS LED THE SCIENTIFIC COMMUNITY TO SEARCH FOR NEW MATERIALS TO MAKE NANOCOMPOSITES BIOFILMS. WITH THE HELP OF NANOTECHNOLOGY, THE MATERIALS THAT MAKE UP THE NEW NANOCOMPOSITES BIOFILM CAN BE MANIPULATED, ACHIEVING AN IMPROVEMENT IN ITS MECHANICAL PROPERTIES AND GRANTING ANTIMICROBIAL POWERS. BIOFILMS BASED ON ELECTROSPUN FIBERS AS A BARRIER MATERIAL CAN PROTECT AGAINST INFECTIOUS MICROORGANISMS. FOR THESE APPLICATIONS, THE ELECTROSPINNING METHOD ALLOWS THE ENCAPSULATION OF ACTIVE AGENTS IN THE POLYMERIC FIBERS. THIS ARTICLE PRESENTS THE DEVELOPMENT OF A NANOCOMPOSITES BIOFILM WITH POTENTIAL USE AS AN ANTIMICROBIAL BARRIER, WHICH INCORPORATES POLYLACTIC ACID MICROFIBERS WITH ACTIVE AGENTS. AMONG THEM, COPPER IONS SUPPORTED ON CHILEAN NATURAL ZEOLITE NANOPARTICLES AND REINFORCED WITH ACETYLATED CELLULOSE NANOFIBERS. THE STUDY BEGINS WITH OBTAINING CELLULOSE NANOFIBERS THROUGH MECHANICAL METHODS. NANOFIBERS WERE ACETYLATED TO ENSURE ADEQUATE DISPERSION IN THE POLYMER MATRIX AND TO IMPROVE THE MECHANICAL PROPERTIES OF BIOFILMS. POLYMERS AND NANOPARTICLES WERE INCORPORATED INTO BIOFILMS THROUGH A DUAL CONFIGURATION (SIMULTANEOUS INJECTION) ELECTROSPINNING STAGE.
