## Description

- description: Polymeric materials can boost their performances by strategically incorporating
    inorganic substances. Heat dissipators are a representative class of such composite
    materials, where inorganic fillers and matrix polymers contribute to high thermal
    conductivity and strong adhesion, respectively, resulting in excellent heat dissipation
    performance. However, due to the complex interaction between fillers and polymers,
    even slight differences in structural parameters, e.g., dispersion/aggregation
    degree of fillers and crosslink density of polymers, may significantly impact
    material performance, complicating the quality management and guidelines for material
    developments. Therefore, we introduce pyrolysis mass spectra (MS) as material
    descriptors. On the basis of these spectra, we construct prediction models using
    a data-driven approach, specifically focusing on thermal conductivity and adhesion,
    which are key indicators for heat dissipating performance. Pyrolysis-MS observes
    thermally decomposable polymers, which occupy only 0.1 volume fraction of the
    heat dissipators; nevertheless, the physical states of non-decomposable inorganic
    fillers are implicitly reflected in the pyrolyzed fragment patterns of the matrix
    polymers. Consequently, pyrolysis-MS provides sufficient information to construct
    accurate models for predicting heat dissipation performance, simplifying quality
    management by substituting time-consuming performance evaluations with rapid pyrolysis-MS
    measurements. Furthermore, we elucidate that higher crosslinking density of the
    matrix polymers enhances thermal conductivity. This data-driven method promises
    to streamline the identification of key functional factors in complex composite
    materials.
