2D-CARTON

A Full-Stack Manufacturer of Real Graphene

As a pioneer in graphene industrialization, we possess not only core technology but also strong capital strength. Backed by a 6000㎡ modern production base and an R&D team of 30+ experts, we have achieved vertical integration from CVD raw materials to finished heating films. As a public company, we adhere to financial transparency and compliance, holding 68+ patents with an annual capacity exceeding 3 million sqm. Choosing 2D Carbonene means choosing a stable, reliable, and technologically advanced long-term partner.

2008

Visionary Layout & Team Formation

Two years before graphene won the Nobel Prize, our founding team keenly recognized its disruptive potential. The core technical team assembled this year to dedicate themselves to fundamental research on CVD (Chemical Vapor Deposition) growth mechanisms, planting the first seed for what would become world-leading mass production technology

2011

Company Founding & Production Line Launch

Changzhou 2D Carbonene Technology Co., Ltd. was officially registered. We established China’s first graphene transparent conductive film production line with an annual capacity of 30,000 sqm in Changzhou, officially launching the journey of graphene industrialization in China

2013

World's First Graphene Capacitive Touch Screen

Moving beyond concepts to the market. We successfully launched the world’s first graphene capacitive touch screen mobile phone. This milestone proved to the world that 2D Carbonene has the hardcore strength to transform nanoscale materials into macro-application products

2015

The First Listed Graphene Company in China

[Stock Code: 833608] Officially listed on the NEEQ, becoming the first graphene enterprise with a full industrial chain to enter China’s capital market. The injection of capital laid a solid foundation for subsequent capacity expansion and technological iteration, elevating brand credibility to new heights.

2018

Focusing on Thermal Management & Solving Power Degradation

Leveraging deep expertise in graphene film conductivity, the company’s strategic focus shifted to “Graphene Electric Heating.” We established the Thermal Management Research Institute and successfully solved the industry-wide problem of heating film power degradation, setting a technical standard for “50-year long-term stability

2021

Capacity Exceeds 3 Million sqm, Entering Industry 4.0

The 6000㎡ production base was fully upgraded. We introduced fully automated Roll-to-Roll production equipment, achieving an annual capacity of over 3 million sqm of graphene heating film. The entire product line passed ISO 9001 quality system certification and rigorous IPX7 waterproof testing

2024

Extreme Cold Testing & Government Project Data

2D-CARTON graphene heating systems were deployed on a large scale in government office buildings in severe cold regions like Suizhong, Liaoning. Real-world data proved that even at -20°C, indoor temperatures remained constant, with operating costs far lower than traditional heating, winning the trust of the B2B market with real data

2025

PV Direct Drive, Building a Zero-Carbon Energy Loop

Launching “3-in-1” Integrated Graphene Heating Flooring and “Agri-PV” solutions. Supporting photovoltaic DC power to directly drive the floor heating system—storing heat by day and releasing it by night. We are transforming buildings from “energy consumers” into “green micro-power stations,” leading the heating revolution in the dual-carbon era.

Precision Slot Die Coating System

The “Heart” of the Heating Film Process. Utilizing advanced Slot Die or Micro-gravure coating technology to uniformly apply nano-scale graphene slurry onto optical-grade PET substrates. This equipment strictly controls coating thickness errors within ±1 micron. This extreme uniformity ensures highly consistent sheet resistance across the entire heating film, completely eliminating risks of local overheating caused by uneven coating.
