Biodegradation and hydrolysis rate of aliphatic aromatic polyester
The biodegradation and hydrolysis rates of an aliphatic aromatic copolyester were measured in manure, food, and yard compost environments and in phosphate buffer solution (pH 1⁄4 8.0) and vermiculite at 58 C. Mineralization, molecular weight reduction, and structural changes determined by DSC, FTIR, and 1H NMR were used as indicators of the biodegradation and hydrolysis rates. Poly(butylene adi...
متن کاملStabilization of Subgrade Soil for Highway by Recycled Polyester Fiber
Subgrade soil stabilization is one of the primary and major processes in the construction of any highway; also environmental authorities are concerned about the growing amount of polyethylene (PET) bottles produced by household sectors. This research in order to study effect of adding recycled polyester fiber on soil engineering properties, especially shear strength and California Bearing Ratio...
متن کاملEffect of fiber surface treatments on the fiber-matrix interaction in banana fiber reinforced polyester composites
Cellulosic bers have been used as cost-cutting llers in plastic industry. Among the various factors, the nal performance of the composite materials depends to a large extent on the adhesion between the polymer matrix and the reinforcement and therefore on the quality of the interface. To achieve optimum performance of the end product, suf cient interaction between the matrix resin and th...
متن کاملAromatic Properties of Fully-benzenoid Hydrocarbons
We consider a family of structurally closely related fully-benzenoid hydrocarbons of increasing number of fused benzene rings. Local and global aromatic properties of such molecules are investigated with a particular interest in investigating the role of the finite size of such molecules in modelling the high-polymer or even graphite. An interesting alternation of local properties for benzene r...
