  text: In this work, the preparation of porous hybrid particle-based films by core-shell
    particle design and convenient film preparation is reported. Monodisperse core
    particles consisting of poly(methyl methacrylate‑co‑allyl methacrylate) (P(MMA‑co‑ALMA))
    were synthesized by starved-feed emulsion polymerization followed by the introduction
    of an initiator-containing monomer (inimer) for subsequent atom transfer radical
    polymerization (ATRP). The inimer shell allowed for the introduction of allylhydrido
    polycarbosilane (SMP-10) under ATRP conditions by grafting to the core particles.
    The functionalization of the prepared core-shell particles was investigated by
    IR spectroscopy (FTIR), scanning transmission electron microscopy (STEM) and solid-state
    NMR combined with dynamic nuclear polarization (DNP). The obtained hard core/soft
    preceramic shell particles were subjected to the melt-shear organization technique,
    enabling a convenient alignment into a colloidal crystal structure in one single
    step without the presence of a dispersion medium or solvent for the designed particles.
    Moreover, the hybrid particle-based films were converted into a porous ceramic
    structure upon thermal treatment. As a result, freestanding ceramic porous films
    have been obtained after degradation of the organic template core particles. Noteworthy,
    the conversion of the matrix material consisting of SMP-10 into the ceramic occurred
    with preservation of the pristine colloidal crystal template structure. Herein,
    the first example of core-shell particle preparation by combining different polymerization
    methodologies and application of the convenient melt-shear organization technique
    is shown, paving a new way to ceramic materials with tailored morphology and porosity.
