Background Polyurethane (PU) is a widely used plastic material that has excellent physical and mechanical properties. However, PU is difficult to recycle due to its complex chemical structure, making the effective disposal of PU waste a pressing issue. Current methods for PU disposal include incineration, which can release harmful toxins into the environment,...

Background Photopolymers are generated from a mixture of photoreactive liquid monomers or oligomers that can solidify upon irradiation of light. These materials exhibit fast reaction kinetics, solvent-free processes, and tunable material properties, which make them attractive for industrial applications. Photopolymers used in industrial applications...

­Background The melting point (Tm) is an important parameter that dictates the physical properties and applications of semicrystalline thermoplastics. Conventional melting transition characterization techniques such as differential scanning calorimetry, ellipsometry, optical microscopy, and X-ray based methods measure Tm by monitoring temperature-dependent...
