Executive Summary
- Polymer science has expanded to a scale and complexity that surface-level searches no longer capture, with millions of possible sequences and hundreds of billions of dollars in market value at stake.
- A new joint report from CAS and PetroChina SAMRI maps the emerging polymer innovation landscape using structure-based search, bibliometrics, patent intelligence, and natural language processing across nearly one million publications.
- The report equips researchers, investors, and IP professionals with the breadth to see the full landscape and the depth to act on it.
From electronics and healthcare devices to clothing and consumer goods, polymers are some of the most consequential materials ever developed. As the field has grown in scale, it’s also become more complex, with millions of possible sequences to create new polymers and hundreds of billions of dollars in market value.
Identifying promising innovations and prioritizing investments are, consequently, more challenging, particularly as organizations must navigate sustainability expectations, cross-industry applications, and geographic realignment of the competitive landscape. To better understand the state of global polymer innovation, CAS and PetroChina (Shanghai) Advanced Materials Research Institute Co. (SAMRI) developed Polymer Frontiers: A Comprehensive Data-Driven Analysis of Emerging Trends.
The resulting analysis in the report demonstrates why CAS is ideally placed to conduct such a comprehensive investigation. The indexed CAS data, in particular chemical substances drove document retrieval — a more robust search strategy than using keywords alone. Other CAS-indexed data including concepts allowed for extensive data analysis. Likewise, SAMRI researchers combine fundamental science expertise with large-scale industrial application knowledge to provide a rigorous global perspective on the real-world impacts of polymer materials science.
The report analyzes nearly one million polymer-related publications from the last decade (2015-2025) and identifies 200+ emerging topics in various fields including polymer types and materials, applications, chemistry and synthesis, fillers and additives, properties and performance, performance and manufacturing, composites, and sustainability.

In a research space as vast and complex as polymers, it’s vital to understand the breadth of innovation and how it’s translating into commercial opportunities. Subject matter experts from CAS crafted a comprehensive structure-based search strategy to uncover relevant publications that show where the field is headed (see Figure 2).

Starting with polymer substances in the CAS REGISTRY®, we accessed over five million publications in the CAS Content CollectionTM, the world’s largest curated scientific database. Applying further search parameters narrowed the results to nearly 950,000 documents, to which we applied a multi-dimensional methodological framework combining bibliometric analysis, patent intelligence, and advanced natural language processing (NLP) techniques.
NLP-based methods reveal emerging innovations
The amount of relevant polymer-related publications called for AI-driven techniques to efficiently categorize them and make sense of the wider landscape. Our methodology involved extracting candidate phrases from abstract, title, and patent claims and used AI-based classification followed by expert validation to refine categorization. The result is extensive CAS Trendscape maps that represent numerous emerging topics in the polymers field (see Figure 3).

This NLP-based analysis guided the selection of topics such as energy storage systems, electronics, membrane and separation and sustainable polymers. All topics showed growth and a sizeable number of documents associated with them for a deeper dive.

Questions and answers
What are the latest trends in polymer research?
A: Polymer research is moving toward materials engineered for specific, high-value applications rather than broad commodity use. Four areas stand out for research volume and growth: energy storage systems, sustainable polymers, flexible electronics, and polymer membranes. Within these, momentum is building around topics such as solid-state battery components, bio-based and recyclable feedstocks, stretchable conductive films, and selective separation membranes.
What are the biggest challenges in polymer development?
Three challenges dominate the field. First, the sheer scale of possible polymer sequences, now in the millions, makes it difficult to prioritize which structures merit synthesis and testing. Second, sustainability expectations are reshaping every stage of the value chain, from feedstock selection to end-of-life recovery, often without established benchmarks. Third, the competitive landscape is realigning geographically, with research output and patent activity shifting across regions. Navigating these pressures requires data infrastructure that connects chemical structures, applications, and commercial signals, rather than relying on keyword searches or isolated metrics.
What is driving growth in the polymer market?
Demand is being pulled by adjacent industries that depend on advanced materials to hit their own performance targets. Electric vehicles and grid-scale storage are accelerating polymer use in battery components and thermal management. Consumer electronics are driving flexible and wearable formats. Water treatment, biopharmaceutical purification, and gas separation are expanding the polymer membrane market. Sustainability mandates are pushing investment into bio-based, recyclable, and degradable polymers across packaging and construction. Together, these pulls explain why polymer applications now represent hundreds of billions of dollars in market value and continue to attract sustained research and patent activity.
