Area of Science:

• Materials Science
• Polymer Chemistry
• Nanotechnology

Background:

• Amorphous polymers often lack sufficient mechanical strength for demanding applications.
• Achieving high transparency and ultra-high strength simultaneously in polymers presents a significant materials science challenge.

Purpose of the Study:

• To develop an ultra-strong and highly transparent amorphous polymer.
• To investigate the role of in situ functionalized nano-crosslinkers in enhancing polymer properties.

Main Methods:

• Fabrication of the amorphous polymer via rapid photopolymerization.
• In situ functionalization of methyl-β-cyclodextrin into a nano-crosslinker using a eutectic system.
• Characterization of the resulting polymer's mechanical properties (strength) and optical properties (transparency).

Main Results:

• An ultra-strong amorphous polymer with strength of approximately 400 MPa was successfully fabricated.
• The polymer exhibits high transparency, exceeding 90%.
• A percolating nanostructured hard-phase network, formed by the functionalized nano-crosslinker, was identified as the source of the exceptional mechanical properties.

Conclusions:

• Rapid photopolymerization combined with in situ nano-crosslinker functionalization is an effective strategy for creating high-performance amorphous polymers.
• The developed material offers a promising combination of ultra-high strength and high transparency.
• The nanostructured hard-phase network is crucial for achieving superior mechanical performance in transparent amorphous polymers.
