Sodium montmorillonite was incorporated into a poly(εcaprolactone)starch blend by means of a ball mill. The structural organization and physical (mechanical, thermal and barrier) properties were analyzed and correlated with the milling conditions.
the physical and biodegradable properties of polycaprolactone (PCL)/cassava starch blend. It was found that particles of cassava starch, after ball milling (0, 60, 90 and 120 minutes), lost their crystallinity as observed by DSC and birefringency. With less crystallinity, particles observed by SEM. easily formed clumps during the blending process.

Ball milling is a simple, fast, costeffective green technology with enormous potential. One of the most interesting applications of this technology in the field of cellulose is the preparation and the chemical modification of cellulose nanocrystals and nanofibers. Although a number of studies have ...
Prior to composite fabrication, the simultaneous exfoliation and alkali treatment is achieved through the synergetic effect of mechanical and chemical actions generated from ball milling in the presence of sodium hydroxide. The tensile strength of starch/MCC composite containing only 2 wt% MCC is increased by 49% compared with that of neat starch.
Scanning electron microscopy and Xray characterization show that the milling process can improve the compatibilization between the PCL and the starch phases, while promotes the dispersion of clay minerals at nanometric level. The milling time strongly influences the mechanical and barrier properties.
Abstract. Polymer blends between lignin, a natural, widely available, nocost material, and Poly(εcaprolactone) (PCL), a biodegradable polymer, have been prepared using the ''clean'', friendly to the environment, technique of the High Energy Ball Milling (HEBM).

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

Compounding. Masterbatches of 1/1 PCL/clay were made by melt intercalation in a thermokinetic mixer model MH50H; and ground in a knife mill. The concentrates were diluted to final clay concentration (3% w/w) with neat PCL in a corotating twin screw extruder CoperionWernerPfleiderer ZSK 18 operating at 8090 o C and 180 rpm, followed by grinding in a knife mill.

Recently, Vertuccio et al. (2009) used highenergy ball milling to prepare nanoclay (Na + Montmorillonite) reinforced PCL/starch blends. The milling process was shown to improve the compatibilization between the PCL and the starch phases, while promoting the dispersion of clay minerals at the nanometric level (Vertuccio et al., 2009). In this ...
