Interface modified polylactic acid/starch/poly ε-caprolactone antibacterial nanocomposite blends for medical applications

Investigating Thermal and Surface Properties of Low‐Density Polyethylene/Nanoperlite Nanocomposites for Packaging Applications

“…According to the results, the LTN nanocomposites have lower temperatures comparing to the LN nanocomposites, which could be due to the addition of silane groups. Although, the decrease in melting temperature in the presence of any type of nanoperlite is negligible, which is in agreement with the previous reports . The crystallinity of the nanocomposites decreases upon addition of nanoperlite regardless of the nanoparticles type, which could be due to the physical hindrance of the nanoparticles that restrict the molecular movement of LDPE, especially for the samples with higher content of nanoperlite.…”

“…The surface free energy of every discrete component of samples was determined using Owens–Wendt by dispersive and polar surface energy (γ d and γ p ) with a set of test liquids on a solid surface, where s and l represent the solid and liquid surfaces, respectively, and θ is the contact angle of liquid droplet on the surface ( Eqs . and ) . After obtaining γ s for all the nanocomposites, the differences based on nanocontents can be compared. …”

Effect of nanoparticle type and content on morphology, rheology, and crystallinity of poly(lactic acid) using titanium dioxide and polyhedral oligomeric silsesquioxane nanoparticles

“…Biocompatible and environmentally friendly materials have received a remarkable interest from both academy and industry within the last two decades majorly due to the adverse influence of petroleum‐based plastics on the environment . Poly(lactic acid) (PLA) is a fully biodegradable polymer that could be produced from renewable resources . PLA is an aliphatic thermoplastic polyester which possesses high modulus, high strength, and good clarity, making it a promising potential replacement for petroleum‐based plastics .…”

Evaluating the effect of hydroxyapatite nanoparticles on morphology, thermal stability and dynamic mechanical properties of multicomponent blend systems based on polylactic acid/Starch/Polycaprolactone

“…Based on another work , 5% of LATC was found to exhibit the optimum results. Interface modified ternary blends based on PLA/PCL/Starch were prepared via melt blending and it was found that LATC particles have induced antibacterial property to the blend . The interfacial affinity among hydrophilic starch and hydrophobic PLA and PCL was further enhanced by establishing interactions between triclosan –Cl groups and PCL ester groups .…”
