Shape-stabilized phase change materials (ss-PCMs) based on silica and butyl stearate were thermally enhanced via the addition of different hexagonal boron nitride particles (BN) to the sol-gel synthesis. The dataset is used in conjunction with the experimental data of the influence of the particle size and surface area of BN on the thermal and mechanical properties of ss-PCMs discussed in Marske et al. (2021). To study the effect of the different BN particles on the hydrolysis degree of the silica network and on the chemical nature of the porogens sodium dodecyl sulfate and poly(vinyl alcohol) used for the ss-PCM synthesis, the ss-PCM samples are measured via High Power Decoupling (HPDEC) Magic Angle Spinning (MAS) Si NMR and attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy, respectively. Additionally, data of the influence of BN on the thermal properties is presented as thermogravimetric analysis (TG). The Si MAS NMR spectra are referenced to tetramethylsilane and show the different silica species in ppm. The different value of wavenumber and intensity of each reference and ss-PCM sample is listed in the IR spectra. The decomposition points of the ss-PCMs are calculated from the TG data via OriginLab. The spectra and data can be used as a reference for other researchers and engineers to use in synthesizing ss-PCMs based on silica and other polymeric materials or as reference for pure BN, SDS, stabilized silica sol and PVA.
基于二氧化硅和硬脂酸丁酯的形状稳定相变材料（ss-PCM）通过在溶胶-凝胶合成中添加不同的六方氮化硼颗粒（BN）实现了热增强。该数据集与Marske等人（2021年）讨论的BN粒径和表面积对ss-PCM热性能和力学性能影响的实验数据结合使用。为了研究不同BN颗粒对二氧化硅网络水解程度以及用于ss-PCM合成的成孔剂十二烷基硫酸钠和聚乙烯醇化学性质的影响，分别通过高功率去耦（HPDEC）魔角旋转（MAS）硅核磁共振和衰减全反射傅里叶变换红外（ATR-FTIR）光谱对ss-PCM样品进行测量。此外，BN对热性能影响的数据以热重分析（TG）的形式呈现。硅MAS核磁共振谱以四甲基硅烷为参考，以ppm为单位显示不同的二氧化硅种类。红外光谱中列出了每个参考样品和ss-PCM样品的波数和强度的不同值。通过OriginLab根据TG数据计算ss-PCM的分解点。这些光谱和数据可为其他研究人员和工程师在合成基于二氧化硅和其他聚合物材料的ss-PCM时提供参考，或作为纯BN、SDS、稳定化硅溶胶和PVA的参考。
