MQ型功能化POSS的设计合成及其应用研究
Silicone Material（2021）
Abstract
通过氯硅烷与中间体多面体笼型聚倍半硅氧烷(POSS)铵盐发生取代反应或含氢POSS的硅氢加成反应制备了多种MQ型功能化POSS,并对其结构进行了表征.初步将环氧基POSS(OG-POSS)经物理共混改性环氧树脂E51,将甲基丙烯酰氧丙基POSS(MA-POSS)经化学共聚改性聚甲基丙烯酸甲酯(PMMA),结果表明,OG-POSS有助于提高环氧树脂的介电性能,MA-POSS对PMMA力学性能的提升有很大的帮助.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
