If your project is still in its early stages, even if it's just an idea, there's no need to worry. We're here to collaborate with you on designing the perfect polymer structure. Once you share your intended application for the polymer, we'll utilize our extensive knowledge and conduct thorough literature reviews to estimate the parameter windows for its properties, based on the intricate relationship between structure and function.
Drawing from years of experience, we'll pinpoint the backbone category, whether aromatic or aliphatic, as it serves as a fundamental determinant of structural characteristics such as rigidity and elasticity. Additionally, we'll identify the reactive group types necessary for subsequent polymerization, be it ester, ether, anhydrides, or others, tailored to your requirements for biodegradability or non-degradability.
Whether it's a homopolymer, a copolymer with random or block configurations, or specialized structures like branched, brush-like, or graft copolymers, or even intricate self-assembled 3D structures like nanoparticles or polymersomes, we'll explore all possibilities. We can also engineer polymers with specific functionalities, such as conductivity or optical properties, by incorporating small compounds through chemical modification of the polymer side chains.
Further refining the polymer's properties involves tailoring parameters like molecular weight distribution, viscosity, glass transition/melting temperature, color, water content, residual solvents, and purity levels, ensuring they align with your application's requirements.
Our approach encompasses a wide array of polymer structures and properties, offering flexibility and customization to suit diverse applications.

Following polymerization, the crude polymer is typically dissolved in an organic solvent and precipitated by the addition of a non-solvent. This process is often followed by repeated washing and drying steps. In cases where various impurities need removal, additional techniques such as extraction and centrifugation may be necessary. However, for achieving a high level of purity, chromatography methods such as Field-flow fractionation (FFF) or Size exclusion chromatography (SEC), along with dialysis using membranes of various molecular weight cut-offs, may be employed to further narrow down the molecular weight distribution and eliminate smaller molecular weight impurities.
Once purified, the polymer undergoes either freeze-drying or vacuum drying, sometimes under elevated temperatures, to eliminate residual solvents or water content. To expedite the drying process, the polymer may be ground into fine powder or pellets before drying.
This rigorous purification process ensures that the polymer achieves the desired level of purity and meets the stringent requirements of various applications.

After polymerization and purification, thorough polymer characterization is essential to fully understand the properties of the polymer product. Clients typically request two key analyses: Gel Permeation Chromatography (GPC) and Nuclear Magnetic Resonance (NMR), which provide crucial information about molecular weight and purity.
Polymer chromatographic characterization techniques such as GPC and SEC separate polymer mixtures into individual components, allowing for the analysis of compositional profiles and measurement of molecular weight distributions.
Thermal polymer characterization involves techniques like Differential Scanning Calorimetry (DSC), which measures parameters like glass transition temperature (Tg), melting temperature (Tm), and crystallization temperature (Tc). Thermogravimetric Analysis (TGA) predicts how polymers react to processes such as heat, oxidation, and decomposition, while Thermomechanical Analysis (TMA) and Dynamic Mechanical Analysis (DMA) assess thermal properties.
Microscopic polymer characterization techniques include Near-Infrared (NIR) spectroscopy imaging, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Atomic Force Microscopy (AFM). These methods offer high-resolution analysis of polymer morphology.
Rheometric polymer characterization evaluates the viscoelastic properties of polymers, crucial for determining polymer processing methods and understanding their impact on final properties.
Mechanical polymer characterization assesses properties such as strength, elasticity, viscoelasticity, and anisotropy. These properties are influenced by interactions between polymer chains, such as stretching and realigning under force, and are vital for determining the material's suitability for various applications.
