General description
Application
PDMS is a material of choice for ophthalmic applications due to its high mechanical strength, transparency, and oxygen permeability. It can be used as a prepolymer to prepare a glucose permeable interpenetrating network of PDMS and poly (N-isopropyl acrylamide (PNIPAAM). These networks can be used in ophthalmic applications.
PDMS can also be used to synthesize fire and heat-resistant polyurethane-PDMS hybrids. The addition of PDMS provides low flammability and thermal stabilization to polyurethane under pyrolytic conditions.
PDMS is used as an additive to prepare TEOS-based stone protective hybrid crack-free xerogels. The addition of PDMS accelerates the gelling process and helps to achieve effective stone protection.

Dr. Tan and researcher introduce recent trends in Self-healing Soft Electronic Materials and Devices. The emergence of smart, functional SHPs will be highly beneficial to the advancement of the next-generation self-healing soft electronic devices. Autonomously self-healing devices could help to minimize the need for repair or replacement of electronics and machines, potentially reducing the cost of materials and reducing electronic waste.
Advances in the area of soft optoelectronics, with a focus on the development of organic optoelectronic devices on shape memory polymers (SMP) is discussed.
Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
