Disaggregation of palygorskite crystal bundles via high-pressure homogenization
Abstract A simple and effective method, high-pressure homogenization, for the disaggregation of palygorskite crystal bundles was reported. The effects of high-pressure homogenization on the structure and properties of palygorskite clay were investigated. The palygorskite crystal bundles were disaggregated very well while keeping the intrinsic aspect ratio of the microfibers after homogenized at 50MPa. Compared to natural palygorskite, the specific surface area (from 192m2/g to 246m2/g), micropore surface area (from 72m2/g to 110m2/g) and micropore volume (from 0.033cm3/g to 0.051cm3/g) of palygorskite were clearly enhanced after homogenization. In addition, a perfect dispersion of palygorskite fibers was obtained after homogenized at 90MPa.
Highlights ► A simple and effective method was proposed to disaggregate palygorskite bundles. ► The effect of homogenizing pressure on structure and property of sample was studied. ► Highly disaggregated palygorskite fibres with intrinsic aspect ratios were achieved. ► A perfect suspension of palygorskite was obtained after homogenizing at 90 MPa.
