“…Additionally, the frame also constrained lateral movement of the PC laminate forcing the polycarbonate to stay in place even after such huge impact. 20,21 The process of making PC laminates using solvent vapor bonding is quite a challenging process. Since the laminates are handmade in normal room conditions, maintaining complete transparency and accuracy of orientation of laminae is compromised.…”

“…This has happened because the toughness of polycarbonate increases significantly due to 20 layers of laminates which is further explained due to the high toughness of PC laminate which was proved from tensile test. Additionally, the frame also constrained lateral movement of the PC laminate forcing the polycarbonate to stay in place even after such huge impact 20,21 …”

Armed vehicles, improvised explosive device blast‐proof vehicles, require their windshields and windows to be transparent and yet be resistant to high‐velocity impact of splinters. Hence, composite which is of ballistic grade and yet transparent is in real need for all these applications. This study is dedicated to finding a practical solution for using transparent polycarbonate (PC) laminate made using solvent vapor bonding for ballistic applications. The solvent that was proved to be best for solvent vapor bonding of polycarbonate sheets was dichloromethane, as the bond strength was observed to be high from the results of lap shear tensile test. The transparency retention is reasonably high when solvent vapor bonding was used and the toughness has increased near to 50% in comparison with nonlaminated PC. In this study, a polycarbonate laminate with dimensions 150 × 150 × 40 mm made using solvent vapor bonding and is tested with two 9‐mm bullets fired with velocity of 430 m/s from a distance of 5 m. The laminae successfully stopped both the bullets without any back face signature and there was no brittle failure as such, rather delamination happened at interface of laminae since it has essentially absorbed the impact energy of bullet.Highlights Solvent vapor bonding of polycarbonate laminate.

“…Lukashenko et al investigated a chemical solvent bonding technique for manufacturing nondetachable PMMA substrates using different solvents such as ethyl acrylate, n-butylacrylate, and vinyl acetate. In particular, vinyl acetate was selected since it exhibited the solvent-bonded seam with smaller change in the working volume of microstructures after bonding [66]. An optimized solvent composition for bonding is a key for good solvent bonding performance.…”

Microfluidics is a multidisciplinary science that includes physics, chemistry, engineering, and biotechnology. Such microscale systems are receiving growing interest in applications such as analysis, diagnostics, and biomedical research. Thermoplastic polymers have emerged as one of the most attractive materials for microfluidic device fabrication owing to advantages such as being optically transparent, biocompatible, cost-effective, and mass producible. However, thermoplastic bonding is a key challenge for sealing microfluidic devices. Given the wide range of bonding methods, the appropriate bonding approach should be carefully selected depending on the thermoplastic material and functional requirements. In this review, we aim to provide a comprehensive overview of thermoplastic fabricating and bonding approaches, presenting their advantages and disadvantages, to assist in finding suitable microfluidic device bonding methods. In addition, we highlight current applications of thermoplastic microfluidics to analyses and diagnostics and introduce future perspectives on thermoplastic bonding strategies.
