TGA: A Sensitive Diagnosis of Thermal Stability of Laser-deposited Materials

Thermal gravimetric analysis is demonstrated as a sensitive technique for determination of thermal stability of laser deposited materials which are typically produced in low quantities. The usefullness of the technique for studies of thermal behaviou...

IR Laser-Induced Modification of Poly(vinyl acetate): Elimination of Monomer and Deposition of Polar Crosslinked Films

IR laser-induced chemical modification of poly(vinyl acetate) (PVAC) has been examined through ablative and non-ablative thermal processing of bulk PVAC, which revealed three previously unobserved decomposition routes. Low fluence-irradiations result...
