Lactide-based (biocompatible/degradable) Polyesters
Polylactide (PLA) is an aliphatic polyester that is of interest in various applications, due to its biodegradability, biocompatibility, and renewable monomer resources. In addition, properties of this polymer can be modified for use in specific applications by copolymerization or blending with other polymers. In our lab, various lactide-based copolymers have been synthesized, e.g., poly(D-lactide), poly(L-lactide), poly(DL-lactide), poly(lactide-co-ethylene glycol), poly(lactide-co-glycidol), poly(lactide-co-ethylene terephthalate). The copolymers are then used in various applications, for example, as fertilizer controlled-release materials, packaging materials, and in biomedical, environmental and energy applications. Micro- and nanoencapsulation techniques and electrospinning methods are employed in the preparation of the materials.
Conventional and Two-Dimensional FTIR Spectroscopy
Infrared spectroscopy is a fundamental analytical technique that is widely used in material characterization. Recently, an advanced methodology, two-dimensional infrared spectroscopy (2D-FTIR) has been developed, which provides notable advantages over conventional FTIR. For example, an improvement in band resolution, simplicity in band assignment, and determination of relative order of responses of specific functional groups to external perturbation, have been achieved. The FTIR and 2D-FTIR techniques have been applied in characterizations of various materials, e.g., polymers, fuels, and minerals.
