1) Raising Hot Melts to a New Level of Performance
최근 PSAs(pressure sensitive adhesives)에 사용되는 접착제 원료의 종류에는 3가지가 있다. ① solventborne acrylics 와 고무, ② aqueous dispersions 그리고 ③SIS/SBS block-copolymer hot melts 가 그것이다. 이중에서도 SIS/SBS hot melts는 급속한 성장률을 보이고 있다. 이처럼 SIS/SBS hot melts가
1 GPa
Elastic modulus Nanoindentation > 6 GPa
Adhesion Tape pull, modified-edge lift-off Delamination-free
Disavantages
Weakens mechanical properties
Lower thermal conductivity
Narrow pore distribution to ensure dielectric constant is homogeneous and isotropic
Pores need to be closed cells to prevent crack propagation and moisture absorption
Need to add silica to seal surface pores

라디칼 중합에 의한 공중합 반응에 있어서, 생성되는 공중합체의 조성은 각 단량체의 조성은 각 단량체의 조성은 각 단량체의 상대적 반응성과 농도에 의해서 조절된다.
어떤 한 단계에서 생성된 공중합체 중의 단량체 M의 몰분율을 F₁그 단
● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for
