Special Issue Information

Dear Colleagues,

In the last decade, we have witnessed massive achievements in the field of silicon nanomaterials. Among them, optical silicon nanomaterials have attracted considerable attention owing to their unique advantages, including strong fluorescence/phosphorescence coupled with robust photostability, rich resource support, low cost, industrial maturity, and good biocompatibility. Extensive efforts have been devoted to developing effective methods for the synthesis and characterization of optical silicon nanomaterials with different nanostructures, facilitating the promotion of this promising material for myriad optical applications. This Special Issue covers new methodologies to synthesize and characterize optical silicon nanomaterials. Attention is devoted to the most promising applications of these systems in the fields of bioimaging, sensing and energy conversion.

The high-hardness and transparent PMMA-based composites play a significant role in modern optical devices. However, a well-known paradox is that conventional PMMA-based composites with high loadings of nanoparticles usually possess high surface hardness at the cost of poor transparency and toughness due to the aggregation of nanoparticles. In this work, ideal optical materials (SiO2/PMMA composites) with high transparency and high surface hardness are successfully fabricated through the introduction of the flow modifier Si-DPF by conventional melt blending. Si-DPF with low surface energy and high transparency, which is located at the SiO2/PMMA interface, and nano-SiO2 particles are homogeneously dispersed in the PMMA matrix. As an example, the sample SiO2/PMMA/Si-DPF (30/65/5) shows outstanding transparency (>87.2% transmittance), high surface hardness (462.2 MPa), and notched impact strength (1.18 kJ/m2). Moreover, SiO2/PMMA/Si-DPF (30/65/5) also presents a low torque value of composite melt (21.7 N⋅m). This work paves a new possibility for the industrial preparation of polymer-based composites with excellent transparency, surface hardness, processability, and toughness. Full article
