A sustainable porous composite material based on loofah-halloysite for gas adsorption and drug delivery

Abstract

We present a quick and straightforward synthesis of a composite from inexpensive materials like loofah and halloysite. New biomaterial showed exceptional carbon dioxide adsorption and release capabilities and good potential for resveratrol delivery.

TiO2/Loofah–Halloysite Bio–Hybrid Composites as Efficient Systems for VOCs Removal

“…Please note that the CO 2 obtained in both tests cannot be ascribed to the loofah degradation, which is stable up to 250 °C (as also detected by TGA) [14,16] . In our case, in fact, the temperature did not exceed 45 °C (see experimental procedures in the Experimental Section).…”

“…1,1'-carbonyldiimidazole was used as a crosslinker, with a ratio of 2 equivalents to halloysite. [14] The TiO 2 used in this work were commercial powders (Merck, TiO 2 anatase nanopowders < 25 nm particle size, 99.7 % trace metals basis), previously characterized by our research group. [15] The TiO 2 nanoparticles (15 wt % respect to the loofahhalloysite support) were dispersed in a water/ethanol solution (55 mL/5 mL) and put in an ultrasonic bath for 30 minutes.…”

“…As reported in our previous work, the amount of H in LH composites was checked through TGA. [14] The experimental procedures, the details of these measurements, and the experimental setup for the VOCs photooxidation in gas-phase are reported in the Experimental Section. Figure 2 shows the thermogram of the TiO 2 /LH composite, which exhibits an onset of degradation temperature at around 250 °C, in line with literature data considering the loofah-based materials.…”

Portable Nanocomposite System for Wound Healing in Space

“…To date, the number of products produced by nanotechnology or containing nanomaterials is increasing. Current applications include healthcare (drug delivery, regenerative medicine, and diagnostics), environmental protection, electronics, cosmetics, and information technology [ 16 , 17 , 18 , 19 , 20 , 21 , 22 ].…”

Real-time observation of compressive fracture of porous material by 10-millisecond 4D X-ray microtomography

“…Porous composite materials [12][13][14][15][16][17][18][19] have attracted attention as materials that have both the flexibility of porous materials and the functions of fillers. Regarding the flexibility of porous materials, they must have excellent shape-following performance on uneven surfaces and compression recovery properties and must be able to be used repeatedly.…”
