Innovative Chemistry STEM Programme:

Introduction to Smart Coating

Program Introduction
A coating is a layer that is applied to the surface of an object for functional, decorative or both purposes. Painting is one of the most conventional types of coating for wall, metal surface or glass surface to retard corrosion or mold formation of the base surface. Smart coating refers to a coating which is able to sense its environment and make an appropriate response to that stimulus.

In this programme, students will learn the most advanced coating technology. Students will attend lectures on the coating theory and chemical instrumentation for coating in the morning. Equipped with the specific scientific knowledge from the lecture, students will make use of what they have learnt to perform exciting experiments in the afternoon. The experiments include to design and fabricate superhydrophobic and heat-resistant coatings, to construct a thermometer by themselves, to handle and analyze data of various paints, and to determine volatile organic compounds (VOCs) in different paints using sophisticated chemical instruments with the latest technology.

Learning should not be confined to classrooms. Other than STEM education, students are going to have a glimpse into our chemistry curriculum and CUHK. Admission talk, laboratory tour, campus tour and CUHK treasure hunt will be arranged for students, so as to make the programme more fruitful and enjoyable for students.

活動簡介

塗層泛指覆蓋物體表面層的物質，一般具有功能性及裝飾性之用途。例如大家最常見的油漆，在生活上就被廣泛使用於牆壁、金屬或玻璃表面，以防止或減慢底層生銹、腐蝕或發霉。

塗層技術不斷發展，近年更突破至智能塗層。智能塗層能夠感知周遭環境，並根據環境的轉變作出相應變化。智能塗層的出現，勢必為人類的生活帶來更多便利。

本活動將介紹尖端塗層科技。上午時段以授課形式為主，同學將會學習塗層的基本原理及化學儀器。下午時段則以實驗為主題，同學將會把上午課堂的科學知識學以致用，親自設計和調配防水和隔熱塗層。同學亦會利用所學知識親動手製造溫度計。在實驗中，同學將會接觸到各種類型塗層的數據，並運用所學技能進行數據分析。除此之外，同學更會操作尖端科技的化學儀器，進行塗層的揮發性有機化合物 (VOCs) 含量檢測。

我們深明學習不應局限於課室內，因此除了STEM教育外，也為同學預備了一系列課外活動，如入學講座、實驗室參觀、校園遊及中大定向，務求增加同學對化學系課程及中大的認識，也令他們有更充實和愉快的活動學習體驗。
