when ballmilling alone was used. The vibrational frequency of the ballmilling device was 3–30 Hz, and the grinding jars were stainless steel with a volume of 10 mL. The size of the milling balls was 10 mm. Initial studies used a rotational frequency of 20 Hz at room temperature for a total of 11 minutes for bromination of 2chlorophenol.
Carbon nano tubes (CNTs), comprising one dimensional (1D) carbon tubes that significantly strengthen the base matrix when added as a reinforcement element. It is light in weight and very low weight fractions (vol% or wt%) of welldispersed CNTs enhance mechanical properties effectively. Due to its poor wettability during liquid mixing, CNTs reinforced composites are mostly prepared by solid ...
