The recent advancements
of poly(methyl methacrylate) (PMMA) as
a transparent flexible polymer material have been utilized in numerous
areas of engineering and materials science. PMMA-based copolymers
demonstrate outstanding mechanical and optical properties owing to
high transparency, lightweight nature, high impact resistance, and
stress relaxation across glass transition temperature. These copolymers
have unique characteristics of retaining optical and microstructural
integrities during successive bending or elongations which make them
an attractive choice for materials of stretchable electronics. In particular, there has been
an escalated rise in the use of methyl methacrylate (MMA)-based transparent
and stretchable copolymer films during the recent decades. Therefore,
we have highlighted these recent developments into a comprehensive
review in order to aid the future progress in these diverse fields.
Herein, we have highlighted the scope of MMA as an important building
block for the synthesis of highly transparent and flexible materials.
The synthetic pathways of these copolymer materials and the resulting
mechanical properties have been discussed. Moreover, the immense scope
of these copolymer films has been highlighted by virtue of their applications
in various industries.
