Biodegradable nanocomposites of cellulose acetate phthalate and chitosan reinforced with functionalized nanoclay: Mechanical, thermal, and biodegradability studies

Abstract

Biodegradable nanocomposites of cellulose acetate phthalate and chitosan reinforced with functionalized nanoclay (NC) were prepared. The NC loading was varied from 0 to 10%. The mechanical and thermal properties have been investigated for these composites. The nanocomposites exhibited enhanced mechanical properties due to the addition of NC. The scanning electron micrographs of the blend specimens also support the above observations. Thermogravimetric analyses were carried out to assess the degradation stability of the blends. The blend shows an increase in the rate of biodegradation and water uptake with higher loading of NC. The exfoliation of NC was analyzed by X-ray diffraction studies. V C 2011 Wiley Periodicals, Inc.

The friction and wear properties of carbon nanotubes/graphite/carbon fabric reinforced phenolic polymer composites

“…[1][2][3][4][5] When the polymer matrix must withstand high mechanical and tribological load, it is usually reinforced with various fillers, such as clay, [6] carbon nanotubes (CNTs), [7] mesoporous silica, [8] grapheme, [9] fibers, [10] or inorganic nanoparticles. [11,12] Among these reinforcing elements, fiberbased fabrics are very unique and outstanding because of their high structure ordering and tightness.…”

Biocidal activity of cellulose materials for medical implants

“…The presence of a solvent in the blend system introduces the polymers-solvent interactions as a function of polymers composition, concentration of polymers solution and temperature, and determines different conformations. Interpretation of surface properties results must be performed starting from CAP 36 The occurrence of hydrogen bond structures in blends can be evidenced from peaks shape and intensity of the absorption band of the hydrogen stretching vibration. 23 The differences observed among the shape, broadening, and shifting of the mentioned peaks for polymer blends suggest the existence of hydrogen bonding, generated by AOH, C@O, and CAOAC groups.…”

Cellulose Nanocomposites

“…Compressive strength was improved by 22%, the tensile strength reached an optimal value with 6% nano filler. Water uptake was reduced in the presence of silane (96). Cloisite increased the water absorption resistance, tensile and bending properties of the low density polyethylene (LDPE)/sawdust blend; maleic anhydride grafted LDPE (MA-g-LDPE) was used as coupling agent in the amount of 3 wt%.…”
