Jiale Shi, Michael J. Quevillon, Pedro H. Amorim Valença, Jonathan K. Whitmer

摘要:

聚合物-表面相互作用对许多生物过程和工业应用至关重要。在这里,我们提出了一种机器学习方法来连接模型聚合物的序列与其粘附装饰表面。我们模拟的粘合剂自由能的$20,000$独特的粗粒度的1D顺序聚合物与功能化的表面相互作用,并建立支持向量回归(SVR)模型,证明廉价和可靠的预测的粘合剂自由能作为序列的函数。我们的工作突出了粗粒度模拟与数据驱动的机器学习方法的集成,用于设计新的功能聚合物,并代表了将聚合物组合物与聚合物表面相互作用联系起来的重要一步。

英文摘要:

Polymer-surface interactions are crucial to many biological processes and industrial applications. Here we propose a machine-learning method to connect a model polymer's sequence with its adhesion to decorated surfaces. We simulate the adhesive free energies of $20,000$ unique coarse-grained 1D sequential polymers interacting with functionalized surfaces and build support vector regression (SVR) models that demonstrate inexpensive and reliable prediction of the adhesive free energy as a function of the sequence. Our work highlights the promising integration of coarse-grained simulation with data-driven machine learning methods for the design of new functional polymers and represents an important step toward linking polymer compositions with polymer-surface interactions.
