Retsch zm 200 rotor mill

PLA in a pellet form was supplied by NatureWorks© (Plymouth, MI, USA) under IngeoTM, 2003D extrusion grade. The most important physical properties of the polymer are as follows: D-isomer content (optical purity) = 4.3%; density = 1.24 gcm⁻³; glass transition temperature (T_g) = 60 °C; and melting temperature (T_m) = 165 °C. PHBHHx in a pellet form was kindly supplied by Kaneka Corporation (Tokyo, Japan) as Aonilex X151 grade with a molar ratio of 3HHx = 10.5 mol. The polymer had the following physical characteristics: density = 1.19 gcm⁻³; T_g = −0.2 °C; and T_m = 130 °C. Halloysite nanotubes were supplied by the Algerian Kaolin Company (Soalka, Jijel, Algeria) and were collected from the Djebel Debbagh mining area in northeastern Algeria (Guelma). Halloysite nanotubes (HNTs) have an average internal diameter of 10 to 30 nm, an external diameter of 30 to 50 nm, a length of approximately 0.1 to 2 microns, a density of 2.1 g cm⁻³, and a specific surface area of 51.4 m²/g [38 (link),41 (link)]. Before use, the raw clay was ground to powder using a Retsch ZM 200 rotor mill (Fisher Scientific, Loughborough, UK). After sieving, microparticles with an average diameter of 25 µm were selected. Maleic anhydride (MA) and dicumyl peroxide (DCP) were supplied by Sigma-Aldrich and used as received.
