Nanocomposite Poly(lactic acid)/sepiolite with Improved Mechanical and Biofilms Formation Properties

Nanocomposites of poly(lactic acid) with sepiolite needles (5 wt.%) were evaluated in terms the mechanical and biofilm formation properties. The nanocomposite exhibited higher values Young�s modulus tensile strength at break compared to PLA, without detriment percent elongation break. These improvements related high aspect ratio nanoclay, polymer-clay interactions, degree dispersion. growth Pseudomonas aeruginosa on surface PLA nPLA materials was promoted different conditions. Medium concentration nutrients used also effect medium physical state (solid or liquid medium). Biofilms formed all However, presented a area coverage microorganisms its surface, possibly due positive effects nanoclay bacterial adhesion.
