Latest Patents

One of his latest patents is titled "Continuous fabrication system and method for highly aligned polymer films." This invention involves a process for the continuous fabrication of highly aligned polymer films. A polymer-solvent solution is subjected to high shear and high temperature in a Couette flow to extrude a thin film that achieves polymer chain disentanglement. The extruded thin film is then frozen, and the solvent is allowed to evaporate, resulting in a dried film. This dried film is mechanically drawn using a constant force, adaptive-thickness drawing system to align polymer molecular chains through plastic deformation. A suitable polymer for this process is ultra-high molecular weight polyethylene.

Another significant patent is "Direct and quantitative broadband absorptance spectroscopy with multilayer cantilever probes." This system measures the absorption spectrum of a sample using a broadband light source that produces light defined within a range of an absorptance spectrum. An interferometer modulates the intensity of the broadband light source across various modulation frequencies. A bi-layer cantilever probe arm is thermally connected to a sample arm with at most two layers of materials. The modulated broadband light is directed towards the sample, absorbed, and converted into heat, causing a temperature rise and bending of the bi-layer cantilever probe arm. A detector mechanism measures and records the deflection of the probe arm to obtain the absorptance spectrum of the sample.
