Materials and methods for cell-mimetics having mechanical properties of biological neural axons are provided. A cell-mimetic device includes an array of fibers comprised of hexanediol diacrylate (HDDA) or an HDDA derivative, and at least one derivative of polyethylene glycol (PEG) selected from the group consisting of: PEG-acrylate, PEG-diacrylate, and any multi-arm PEG-acrylate.

Disclosed herein is a preparation method of homopolymer nanoparticles without using a surfactant. The homopolymer nanoparticles prepared thereby are expected to be widely used not only as a template of a semiconductor metal oxide, a drug delivery system (DDS), an electron transport layer (ETL), and a seed having vertical structural shape, but also in a high precision field such as replacement of an organic device polystyrene bead film.

In accordance with the present invention, there are provided methods to improve the performance properties of thermoset polymer resins prepared by the activation of one or more reactive monomer(s) which is(are) initiated by way of a first reaction mechanism at a defined temperature (typically a temperature in the range of 40-200 C.). Exemplary performance properties which are improved by the invention methods include enhanced thermal stability, tensile strength (which is maintained in spite of exposure to elevated temperatures over extended periods of time), adhesive properties (which are substantially maintained in spite of exposure to elevated temperatures over extended periods of time), weight loss (which is minimized in spite of exposure to elevated temperatures over extended periods of time), dielectric strength (which is substantially maintained in spite of exposure to elevated temperatures over extended periods of time), and the like.
