An efficient method of preparing nanostarch using high-intensity ultrasonic irradiation and acid hydrolysis was discussed. The transmission electron microscope (TEM) showed that the nanosized starch particles were in shape of sphere with the size of 80-120 nm, and their surfaces were rough with many flocci. The Fourier transform infrared spectrometer (FT-IR) revealed that the products ...

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.
The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power …
Nano-sized starch particles were prepared from potato starch via high-energy ball milling, which is a purely physical method. Scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry, and viscometer were used to analyze the morphology and characteristics of the as-prepared nanoparticles.
The graft-copolymers starch-g-PCL and starch-g-PLA can be completely biodegraded under natural conditions and exhibit improved mechanical performances. To introduce PCL or PLA segments onto starch, the ring opening graft polymerization of ε-caprolactone or L …
To obtain microparticles normally ball milling or fluid energy milling are used . These techniques require the application of mechanical energy to breakdown particles . It is quite common to use grinding balls made of glass, ceramics, or strong polymers . However, to obtain nanoparticles a different approach is required: wet milling.
